Anti-Inflammatory Herbal Medicines ( We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies)

Medicinal plants and their secondary metabolites are progressively used in the treatment of diseases as a complementary medicine. Inflammation is a pathologic condition that includes a wide range of diseases such as rheumatic and immune-mediated conditions, diabetes, cardiovascular accident, and etcetera. We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies. Curcuma longa, Zingiber officinale, Rosmarinus officinalis, Borago officinalis, evening primrose, and Devil’s claw are some of the introduced medicinal herbs in this review. Since the treatment of inflammation is not a one-dimensional remedy, this review tries to reach a multidimensional therapeutic approach to inflammation with the help of herbal medicine and modification in lifestyle.

Inflammation is a defense response of our body to hazardous stimuli such as allergens and/or injury to the tissues; on the other hand, uncontrolled inflammatory response is the main cause of a vast continuum of disorders including allergies, cardiovascular dysfunctions, metabolic syndrome, cancer, and autoimmune diseases imposing a huge economic burden on individuals and consequently on the society .

There are various medicines for controlling and suppressing inflammatory crisis; steroids, nonsteroid anti-inflammatory drugs, and immunosuppressant are the practical examples of these medications which are associated with adverse effects while in practice our goal is to apply minimum effective dose by the highest efficacy with the least adverse effects. Thus, we need to apply natural anti-inflammatory factors within medication therapy to achieve increased pharmacological response and the lowest degree of unwanted side effects.

Herbal medicines are promoting subjects in medicine and, of course, we have to increase our knowledge about them. Complementary, alternative, and traditional medicines are the pivotal source of herbal medication guidance, but surely modern medicine must prove these guidelines through scientific methods before using them in practice. In this review, we have endeavored to assess the plants and the most clinical evidence of their anti-inflammatory effects.

Take a look at this collection The Lost Book Of Remedies, taken word for word out of a circa 1845 manual.

What is The Lost Book of Remedies? The Lost Book of Remedies PDF contains a series of medicinal and herbal recipes to make home made remedies from medicinal plants and herbs. Chromic diseases and maladies can be overcome  by taking the remedies outlined in this book. The writer claims that his grandfather was taught herbalism and healing whilst in active service during world war two and that he has treated many soldiers with his home made cures.

How does it work?

The premise is that many modern day medicines work on the basis that they treat the symptoms and not the cause, but contained within The Lost Book of Remedies are a number of tinctures and tonics made from plants and leaves that will treat the cause of the illness, thus eradicating the disease altogether.

The book is a direct copy of the little notebook carried around by the author’s grandfather when treating his patients.  However, the illustrations of the plants have been updated to photographs so that they are easier for you to identify.

Curcuma longa

Curcuma longa (common name is Turmeric in English, زردچوبه in Persian, cúrcuma in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i001.jpg in Hindi, and عقدة  الصفراء in Arabic) is an Indian indigenous plant . The most important secondary metabolite of C. longa is curcumin, which is responsible for anti-inflammatory effect of this plant .

Many clinical trials have been done for proving the anti-inflammatory effect of curcumin. Their results suggest that curcumin can be effective in improving inflammation of rheumatoid arthritis (RA) and reducing clinical manifestation of RA, such as joint swelling and morning stiffness in comparison with phenylbutazone which is used as a positive control. Also, curcumin was tested in patients with anterior uveitis; after 2 weeks, exhaustive remission occurred [. The effectiveness of curcumin in patients with dyspepsia and/or gastric ulcer was proved by another clinical trial. In this study, subjects experienced remission after 12 weeks (maximum) . Curcumin is beneficial in irritable bowel syndrome (IBS) treatment  and also works as a reducing agent to delayed graft rejection (DGR) after kidney transplant surgery. Curcumin likewise has a beneficial effect in inhibition of inflammatory bowel disease (IBD) and reduction in sedimentation rate in patients who suffered from IBD. It is also proven to be beneficial in maintaining amelioration of ulcerative colitis  and psoriasis (by the selective prohibition of phosphorylase kinase) .

Zingiber officinale

Zingiber officinale (common name is ginger in English, زنجبیل in Persian, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i002.jpg in Hindi, and الزنجبيل in Arabic) is a native plant from south-east Asia .

Oral administration of Z. officinale extract has shown different and inconsistent effects, depending on the quantity of consumption. Although administration of squeezed ginger extract to mice one time or twice has elevated the tumor necrosis factor-α (TNF-α) in peritoneal cells, long-term consumption of the extract has increased the serum corticosterone level and has reduced proinflammatory markers . Z. officinale was also tested in type 2 diabetic patients with low-grade inflammation; after 2 months of treatment, serum level of TNF-α and high-sensitivity C-reactive protein (hs-CRP) were decreased definitely . In patients with osteoarthritis, ginger had not only efficacy in pain improvement identical to Diclofenac 100 mg but also no side effects . Ginger extract has been compared to Ibuprofen and Indomethacin in OA patients; the results have exerted improving function of Ibuprofen, Indomethacin, and ginger extract equally in pain score . Ginger powder has had ameliorative effect in musculoskeletal and rheumatism patients through inhibiting cyclooxygenase and lipoxygenase pathway in synovial fluid .

Rosmarinus officinalis

Rosmarinus officinalis (common name is Rosemary in English, رزماری in Persian, Romero in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i003.jpg in Hindi, and روزماري in Arabic) is native in the Mediterranean area .

In an open-label trial, the effects of rosemary extract have been assessed in patients with osteoarthritis (OA), rheumatoid arthritis (RA), and fibromyalgia during 4 weeks; hs-CRP (an index for inflammation presence) was decreased noticeably in patients who had demonstrated augmentation in this index; by the way, reduction in inflammation related to pain score was observed during the treatment but remission has not occurred in fibromyalgia scores. There is evidence that confirms anti-inflammatory potential of R. officinalis in molecular scope; according to this, rosmarinic acid could disturb complement system activation easily by inhibiting C3b attachment; the dose required for making this effect is very low (34 µM) . Furthermore, rosemary’s extract has shown gastroprotective action against gastric ulcer, even better than Omeprazole; this advantage is because of inhibition activity of rosemary in neutrophils infiltration and reduction in proinflammatory mediators: TNF-α and IL-1 . Nevertheless, in another preclinical study on rats, high dose of rosemary extract (500 mg/kg) has reduced testosterone and spermatogenesis that led to infertility . This plant has had topical anti-inflammatory in wound healing in mice . Carnosic acid in R. officinalis has interacted with CYP3A4 and CYP2B6 substrate and likewise has had toxicity in human hepatocyte with EC50 value identical to Tamoxifen .

Borago officinalis

Borago officinalis (common name is Borage in English, گل  گاوزبان in Persian, Borraja in Spanish, and لسان  الثور-حمحم in Arabic) is a member of Boraginaceae family and is native in European area and north of Africa.

This plant is a rich source of gamma linoleic acid (GLA), which contains 25% of GLA, by elevating prostaglandin-E (PGE) level that leads to cyclic adenosine monophosphate (cAMP) augmentation; GLA could count as a strong suppressor of TNF-α. The mechanism mentioned above can clarify the anti-inflammatory effect of borage oil in rheumatoid arthritis (RA). Regarding this pathway, borage has contraindication during pregnancy because of the miscarriage risk . Antirheumatoid arthritis’s potential of borage seed oil was assessed in 2 RCT as follows: in the first study, 1.4 g/day borage seed oil has been compared with placebo in RA patients; 36.8% amelioration occurred in the treatment group at the end of 6-month therapy. In the second study, 2.8 g/day of borage seed oil was taken by patients during 6 months; at the end of treatment, the amelioration percent of RA manifestation was noticeable: 64% in the treatment group compared with 21% in the control group . Likewise, the anti-inflammatory effect of borage oil was tested in patients with atopic dermatitis. 12 clinical trials were performed to evaluate the effectiveness of this herb in ameliorating in atopic dermatitis. 5 of those have proved the anti-inflammatory effect and 2 of those have recorded improving in some patients, although in the rest 5 trials there has not been any observation for remission.

 Oenothera biennis (Evening Primrose)

Oenothera biennis (common name is evening primrose in English, گل  مغربی  in Persian, Onagri in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i004.jpg in Hindi, and زهرة  الربيع  المسائية in Arabic) is a member of Onagraceae family which is native in Central America .

GLA, linear aliphatic alcohols (e.g., Tetracosanol), and phenolic compound (ferulic acid) are the active components of evening primrose oil which have had protective roles against proinflammatory markers. This oil has sterols such as β-Sitosterol and Campesterol that have had modulator effect on nitric oxide (NO), TNF-α, IL-1β, and thromboxane B2 (TXB2) leading to suppressing COX-2 gene expression; because of these reasons, the primrose oil has a greater anti-inflammatory effect than borage oil. The effectiveness of evening primrose oil with hemp seed oil has been clinically assessed in multiple sclerosis (MS) patients. Patients with MS (a chronic inflammatory disorder) have randomly taken hemp seed/evening primrose oil and placebo. Significant reduction in IFN-γ and IL-17 has occurred in the treatment group. The relapse rate of the disease has been also alleviated in the treatment group; this study has shown the immunomodulatory impression of these oils and their components . In an RCT on RA, researchers have recorded subjective improvement and reduction in using NSAIDs without any improvement in clinical measurements . Likewise, patients have demonstrated remission in morning stiffness with no clinical changes in articular index or pain . And no significant amelioration in target therapy group was the main outcome of a clinical trial on 18 patients with RA after 12 weeks .

Harpagophytum procumbens (Devil’s Claw)

H. procumbens (common name is Devil’s claw in English, پنجه  شیطان in Persian, Garra del Diablo in Spanish, and مخلب  الشيطان  in Arabic) is a member of Pedaliaceae family . Among its abundant metabolites, Harpagoside has been substantiated as an anti-inflammatory component . Root’s extract of Devil’s claw has been claimed to possess inhibition potential of NO, inflammatory cytokines (IL-6, IL-1β, and TNF-α), and PGE2, as well as prevention of arachidonic acid metabolism and eicosanoid biosynthesis, leading to COX-2 inhibition and reducing inflammation . In another preclinical study, devil’s claw has shown no efficacy in improving carrageenan-induced edema in the hind foot of the rat. Over an RCT, the effectiveness of Devil’s claw in osteoarthritis remission has been assessed. At the end of treatment period, anti-inflammatory effects of H. procumbens have been observed . In contrast, in a pilot study which has been carried out on patients who have suffered from arthritic disease (RA and psoriatic arthropathy), researchers have not observed any remission or subjective and objective improvement with 410 mg TDS of H. procumbens’s liquid extract after 12 weeks . Gastrointestinal upset is the main side effect of this plant which leads to contraindication in patients with gastric or duodenal ulcers, gallstone, and diabetes .

Boswellia serrata

Boswellia serrata (common name is Indian Olibanum in English, کندر  in Persian, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i005.jpg in Hindi, and الـلُّبَّـان  in Arabic) is an oleo gum resin of Boswellia tree, which is native in India .

Efficacy of Boswellia serrata extract in patients with osteoarthritis has been substantiated; dramatic alleviation in the frequency of joint swelling and pain and augmentation in joint flexibility and walking distance have been observed at the end of treatment period . Likewise, a significant reduction in erythrocyte sedimentation rate (ESR), morning stiffness, and NSAID administration requirement during therapy has occurred in rheumatoid arthritis patients within another clinical trial . In one pilot study which has been carried out on patients with chronic polyarthritis, no significant remission has been observed in patient’s manifestations after 12 weeks of therapy with extract of B. serrata; just minor attenuation in NSAIDs requirement has been recorded . Collagenous colitis is an inflammatory bowel disease (IBD) and B. serrata has been clinically effective in the process of ameliorating this disease in target therapy group compared to the placebo group . The combination of B. serrata with C. longa and Glycyrrhiza glabra has been effective on improvement of asthmatic patient’s symptoms; also, in this study, treatment group has demonstrated significant diminishing in plasma level of leukotriene C4 (LTC4), NO, and malondialdehyde after 4 weeks . Modulating in inflammatory mediators (TNF-α, IL-1β, IL-6, IFN-γ, and PGE2) by B. serrata extract has been proved in in vivo and in vitro studies. Boswellic acid is the main component of this gum which can inhibit C3 convertase and suppressed classic pathway of complement system . Likewise, it has had topical anti-inflammatory impress as well as systemic effects .

Rosa canina

Rosa canina (common name is Dog rose in English, نسترن  وحشی in Persian, escaramujo-tapaculo in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i006.jpg in Hindi, and ورد  الکلب-ورد  السياج- النسرين in Arabic) is a member of Rosaceae family.

The effectiveness of rosehip has been assessed in OA and RA patients. The outcomes of these studies were as follows: the patients, who have suffered from OA, have experienced alleviation in pain, rescue medication consumption, and stiffness and a significant reduction in CRP which have been observed after treatment with this plant . It should be noted that anti-inflammatory effect of rosehip refers to the seed, but not its shell. The latter claim has been substantiated via two clinical studies which have been done on OA patients . Likewise, rosehip powder has reduced ESR and improved quality of life in RA patients; thus, it might be used as a supplement besides the standard treatment of RA . In contrast, 10 g of rosehip powder per day, during 1 month, has no anti-inflammatory effect on patients with RA . The ethanol extract of rosehip was fractioned by some solvents with different polarity; ethyl acetate and butanol fraction have had anti-inflammatory effects in delayed phase of inflammation process through inhibition of PGE1 in mice . Since n-hexane and dichloromethane extracts of this plant’s fruit have had a downregulatory effect on COX-1, COX-2, and LTB4, these fractions are rich sources of unsaturated fatty acids . Galactolipid is an active component in rosehip powder which its NO inhibitory potential has been confirmed through laboratory and in vitro studies .

 Urtica dioica

Urtica dioica (common name is stinging nettle in English, گزنه  in Persian, Ortigamayor in spanish, and القراص  الكبير  in Arabic) is a member of Urticaceae family .

Nettle leaf has been investigated to prove its anti-inflammatory effect in a pilot study. 50 mg Diclofenac per day was administered to patients with acute arthritis together with 50 mg infusion of Urtica dioica orally. This remedy has caused remarkable attenuation in CRP level and some patients’ complaints for 200 mg Diclofenac per day; according to these outcomes, U. dioica when combined with NSAIDs have an outstanding synergistic effect . Topical effectiveness of nettle leaf has been assessed in osteoarthritis of thumb through RCT; significant alleviation in pain, stiffness, and anti-inflammatory and analgesic therapy requirements have been observed . The combination of nettle leaf with rosehip and willow bark has suppressed IL-1β and COX-2 in chondrocytes. In this in vitro study, chondroprotective and anti-inflammatory effects of this botanical extract have been proved . Leaf extract of U. dioica has had inhibitory potential on proinflammatory transcription factor NF-κB (scientific studies have shown elevation in NF-κB in synovial fluid of RA patients) . This extract has had anti-inflammatory potential in allergic rhinitis by the following pathways: antagonizing H1-receptor, reducing of PGD2 production (allergy specific prostaglandin), and inhibitory effect on mast cell tryptase.

Uncaria tomentosa

U. tomentosa commonly known as cat’s claw in English, uña de gato in Spanish, پنجه  گربه in Persian, and مخلب  القط  in Arabic. It belongs to Rubiaceae family and it is an indigenous plant in Amazon and Central America forests .

The efficacy and safety of this plant in improving OA of the knee have been tested on 45 patients who have been divided into 2 groups (placebo and active); the active group has demonstrated some degrees of remission after 4 weeks by inhibiting TNF-α and diminishing PGE2 production . In a 24-week double-blind placebo-controlled trial which has been performed for evaluating the effect of high purified extract of U. tomentosa in RA patients, this extract has been administered along with Sulfasalazine or Hydroxy chloroquine; modest benefit of this herb in alleviating pain, swelling, and tenderness of joint has been shown in the treatment group in comparison with the placebo group . There is a report of U. tomentosa causing remarkable remission in enteritis in rats which has been observed . Edible extract of cat’s claw has had protective action against respiratory inflammation in mice . Pivotal mechanism of cat’s claw is inhibition of iNOS and NF-κB expression that in turn have downregulated TNF-α, IL-1α, 1β, 10 and 17 successively. Also, little inactivation effect on COX-1 and COX-2 has been expressed through an in vivo study . This plant’s bark has demonstrated anti-inflammatory action exactly the same as dexamethasone in an animal model, while it has attenuated about 40% of IL-4 while dexamethasone has not.

Salvia officinalis

Salvia officinalis (commonly known as sage in English, مريم  گلی in Persian, salvia in Spanish, and قصعين  طبي in Arabic) is a member of Lamiaceae family .

Carnosol and carnosic acid are phenolic diterpenes which have had anti-inflammatory activity . These two components could have inhibited PGE2 production via microsomal PGE2 synthase-1 inhibition. Chloroform extract of sage leaves has shown atopic anti-inflammatory effect in mice . However, sage essential oil has not shown any immunomodulatory effect in mice which had underwent cyclophosphamide-mediated immunosuppression . It is also worth mentioning that Halicioglu et al. have reported generalized tonic-clonic seizures following accidental exposure to sage oil in a newborn and a child .

 Ribes nigrum

Ribes nigrum (common name is blackcurrant in English, آنگور  فرنگى  سياه in Persian, Casis in Spanish, and الكشمش  الأسود in Arabic) oil is a rich source of n-6 polyunsaturated fatty acid (PUFA), γ-linoleic acid, and α-linoleic acid .

In one clinical trial which has been fulfilled on RA patients during 6 weeks, researchers have investigated the effect of blackcurrant oil (BCO) on patients; outcomes were as follows: attenuation in morning stiffness in the experimental group and reduction in proinflammatory mediators including IL-1β and TNF-α in peripheral blood monocytes . After 24 weeks of treatment period with BC seed oil, disease activity symptoms of RA patients have been reduced. Overall, no significant differences in clinical signs and symptoms have been recorded between the placebo and the case group . Also, BC seed oil has a moderate reinforcement effect on the immune response and inhibitory effect on the PGE2 biosynthesis in 40 healthy volunteers older than 65 years . In another clinical study, 12 healthy subjects have consumed BC oil; attenuating in LTB4 biosynthesis via polymorphonuclear-neutrophil (PMN) and increasing of dihomo-γ-linoleic acid in PMN’s phospholipids have been observed . BC skin extract could reduce heat shock protein (HSP70 and HSP90), COX-2, and NF-κB expression in rats which were under diethylnitrosamine (hepatocarcinogen) exposure .

 Persea americana/Glycine max

Persea americana (common name is Avocado in English, آووکادو  in Persian, árbol in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i007.jpg  in Hindi, and  الزِبدِيّة- الأفوكاتة in Arabic) is a native fruit in Central America  and belongs to Lauraceae family. Glycine max (common name is soybean in English, سویا  in Persian, soja in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i008.jpg in Hindi, and فول  الصويا in Arabic) is a member of Fabaceae family, native to East Asia.

In a prospective multicenter, 3-month randomized control trial, 153 OA patients have been enrolled and treated with Avocado/soybean unsaponifiables (ASU) along with NSAID; after 45 days of therapy, NSAID requirement has diminished but no significant changes have occurred in patients’ pain scores . In three clinical trials which have been carried out on OA patients, the effectiveness of ASU has been assessed. Two of them have demonstrated reduction in Lequesne’s functional index (LFI), pain, and disability; likewise, more than 50% attenuation in NSAID requirement has been observed in 71% of patients in the case group versus 36% in the control group, but in the last trial, no intergroup changes have been reported in joint space width (JSW) which has been considered as primary endpoint and no amelioration has been reported in clinical investigations . During 3 years of follow-up of the hip in OA patients taking ASU, no improvement in JSW has been recorded, but 20% prevention of JSW exacerbation has occurred . ASU also has been administrated to 100 patients with linear scleroderma and morphea; this study has shown a beneficial effect of ASU in preventing atrophy, deformity, and contracture, if the treatment with ASU has been initiated at an early stage of the disease . Topical and dietary administrations of Avocado and soybean extract have been assessed in patients with mild to moderate vulvar lichen sclerosus (VLS). At the end of 24 weeks of treatment period, main sign and symptom of disease have been diminished significantly .

2.14. Elaeagnus angustifolia

E. angustifolia (common name is Oleaster in English, سنجد in Persian, and  الخلاف  ضيق  الأوراق-الزيزفون  السوري  in Arabic) is a member of Elaeagnaceae family .

The effectiveness of Oleaster in the treatment of oral lichen planus (OLP) lesion has been evaluated in an RCT with 28 patients. Seventy five percent and 50–75% attenuation in pain and lesion size, respectively, have been observed in the case group . In another randomized clinical trial which has been carried out on 90 knee OA female patients, a significant attenuation in TNF-α and matrix metalloprotein-1 (MMP-1) (proinflammatory mediators) and alleviation in IL-10 (an anti-inflammatory cytokine) have been reported in active therapy group . Oleaster extract has demonstrated an anti-inflammatory effect in an animal model but this effect was not significant in comparison with sodium salicylate . Aqueous extract of this fruit has shown anti-inflammatory properties in mice through COX-1 and COX-2 inhibition; the evidence has exerted no correlation between corticosterone level and that of anti-inflammatory action .

Vaccinium myrtillus

Vaccinium myrtillus (commonly known as bilberry in English, بلوبرى  آروپایى in Persian, arándano in spanish, العنبية  الآسية in Arabic) is a member of vaccinium family .

In a randomized clinical trial, which has been carried out on 27 patients with metabolic syndrome who have received 400 g fresh bilberry daily, outcomes have been reported as follows: diminishing in hs-CRP, IL-6, and IL-12 and circulating LPS concentration in the active group . Bilberry has caused remission in 63.4% of 13 ulcerative colitis patients after 6 weeks and significant reduction in mayo score and fecal protection level has occurred . No changes have been observed in anti-inflammatory peptides (monocytes chemotactic protein-1) of diabetic patients after one capsule of concentrated bilberry extract (36% w/w anthocyanins) administration per day .

Olea europaea

Olea europaea (commonly known as Olive in English, زیتون in Persian, Olivera in Spanish, An external file that holds a picture, illustration, etc.
Object name is APS2016-9130979.i009.jpg in Hindi, and الزيتون in Arabic) is a species of Oleaceae family .

The positive effect of extra virgin olive oil (EVOO) on modulating postprandial plasma lipopolysaccharide, proinflammatory cytokines, TXB2 and LTB4, and diminished performance in risk of coronary heart disease has been demonstrated in healthy individuals and metabolic syndrome patients . Oral olive oil has accelerated wound healing process and has alleviated hospitalizing duration in deep second-degree and more burn wound patients in comparison with sunflower oil (SFO) . Also, disease activity index and tumor incidence of ulcerative colitis-associated colorectal cancer and proinflammatory cytokines in mice have been alleviated after EVOO enriched diet consumption compared with that of SFO-fed mice .

3. Conclusion

The amount of the plants which have been asserted to possess anti-inflammatory effect is so much that evaluating all of them is out of the scope of this paper; thus, we have sufficed to mention the herbs about which there is more evidence.

Herbal medicine is one of the most important aspects of complementary medicines. There are many studies which have been asserted the role of several herbs in inflammation remission. We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies; of course, clinical data is more reliable than others; among our research data, the Curcuma longa had the most clinical evidence about different inflammatory disorders such as RA, uveitis, and IBD. Also, other listed herbs have demonstrated good performance in clinical and experimental anti-inflammatory tests. Inflammation process has various mechanisms and numerous treatment methods consequently. Plenty of cytokines participate in enzyme activation (such as phospholipase A2), mediator release, fluid extravasation and vasodilation, cell migration, and finally tissue damage which generally have been named inflammation (Figure 1). Biochemical outcomes of the experimental studies clearly show the potential role of herbs in activation or inhibition of proinflammatory cytokines (Table 1), although more clinical studies with larger participants and meta-analyses could dissolve some conflicts. The amount of the plants which have been asserted to possess anti-inflammatory effect is so much that evaluating all of them is out of the scope of this paper.

Note: other mechanisms may also exist but we could not cover all of them.

It should be noted that the word “natural anti-inflammatory” refers to natural compounds, lifestyle, exercise, and sleep and eating habits. There are numerous studies on natural compounds and herbal medicines issues but those outcomes are various and inconsistent; sometimes, the method of evoking extract has direct impact on the chemical constituents and it must be considered because the pharmacological effect of each medicinal herb is the result of plenty of metabolites combination and their synergistic effects; perhaps, it is one of the reasons of paradoxical results. In another aspect, considering side effects, contraindication, and pregnancy properties of plants is an important issue, which requires great caution on the part of the practitioner, but almost there is no reliable evidence about these. Further evidence-based studies and meta-analyses perhaps could create more clear vision and approach for the health professionals.
