Commiphora

Commiphora: A Comprehensive Reference

1. Identity and Botanical Classification

1.1 Taxonomy and Nomenclature

The genus Commiphora belongs to the family Burseraceae and comprises about 150–200 species, most of which grow in the dry bushlands of tropical Africa and Madagascar, Arabia, India, and South America. The genus name Commiphora originates from the Greek words kommi meaning "gum" and phoros meaning "bearing." It was first used in 1797 by Jacquin, who described the first specimen from Madagascar.

The most pharmacologically studied species within the genus are:

• Commiphora myrrha (T. Nees) Engl. (syn. C. molmol) — the primary source of the oleo-gum resin known as myrrh, native to northeast Africa and the Arabian Peninsula.
• Commiphora wightii (Arn.) Bhandari (syn. Commiphora mukul (Hook. ex Stocks) Engl.) — the source of guggul resin, used in Ayurvedic medicine.
• Commiphora erythraea — a species of the Arabian Peninsula producing a resin distinct from but related to myrrh.
• Commiphora gileadensis — source of the historical "Balm of Gilead."

Myrrh, a natural oil gum resin, is harvested from certain tree species of the genus Commiphora, dominated by Commiphora myrrha (T. Nees) Engl. or Commiphora molmol. It is mainly produced in Somalia, Ethiopia, the southern Arabian Peninsula, India, and other regions in Africa.

1.2 Morphology and Resin Production

The genus Commiphora consists of low shrubs or trees, with heights rarely exceeding 3 m, having many irregular spiky coarse branches. When the bark of these plants is damaged, they secrete an aromatic oleogel resin. Most species of Commiphora are deciduous and for much of the year are without leaves, making identification difficult; bark characteristics are then used to identify the trees. The bark of most species peels off in papery pieces and flakes, often with a greenish layer underneath.

The resins exuded from stem incisions consist of a water-soluble portion (30–60%), an essential oil fraction (3–8%), and an alcohol-soluble resin (25–40%) rich in terpenoids and steroids.

1.3 Common Forms and Preparations

The primary commercial and medicinal preparations of Commiphora species include:

• Crude oleo-gum resin (myrrh): the dried exudate from the bark, sold in lump or granule form and used as tinctures, decoctions, or for direct topical application.
• Essential oil: Phytochemical studies show that myrrh contains terpenoids (monoterpenoids, sesquiterpenoids, and volatile/essential oil), diterpenoids, triterpenoids, and steroids. Its essential oil has applications in cosmetics, aromatherapy, and perfumery.
• Guggulipid / standardized extracts: Guggul is the herbal extract from the resin of the Commiphora mukul tree, widely used in Asia as a cholesterol-lowering agent based on Indian Ayurvedic medicine. In modern supplements, the extract is typically standardized to a defined percentage of guggulsterones.
• Tinctures and liquid extracts: Ethanol and water-based extracts are used in Western herbal medicine and in clinical research contexts.

2. Traditional and Historical Use

2.1 Ancient Egypt, Middle East, and the Mediterranean

Myrrh, derived from Commiphora myrrha, has been valued since biblical times for its use in incense, perfumes, and traditional medicines. It was a key commodity along ancient land and maritime trade routes connecting Africa, the Middle East, and the Mediterranean world, at times valued as highly as gold. Myrrh was traditionally used in the ancient world as an insect repellent, incense for religious rituals, and in embalming the dead. Physicians also took advantage of its medicinal properties, treating various ailments including wounds, diseases such as leprosy and syphilis, and to help with digestion and menstruation.

2.2 Ayurvedic Medicine (India)

Already 2000 BC, the Atharva Veda, an ancient Ayurvedic script, describes Commiphora oleogum resin as an effective herbal drug. In the Ayurvedic medical text Sushruta Samhita (from around 600 BC), the resin from the mukul myrrh tree (Commiphora mukul) is prescribed as treatment for a number of illnesses. Revered in Ayurvedic medicine for over 3,000 years, guggul is primarily valued for its oleo-gum resin, which contains bioactive compounds, most notably guggulsterones. It has been used in Ayurveda since time immemorial for the treatment of a variety of disorders such as inflammation, gout, rheumatism, obesity, and disorders of lipid metabolism.

The Indian species Commiphora wightii is used in the treatment of diseases in Ayurveda, the traditional medicine of India. Unfortunately, the plant has become endangered because of its slow growth rate, poor seed germination rate, and excessive and unscientific tapping for its gum resin by pharmaceutical industries and religious practitioners.

2.3 Traditional Chinese Medicine

The medicine of myrrh has a special fragrance and was first known as a spice in the Tang Dynasty. Its taste is punchy and bitter, and its character is described as flat. It has the effect of dispersing stasis and calming pain, reducing swelling, and generating muscle. As a traditional Chinese medicinal material imported from China, it has a long medicinal history. In Traditional Chinese Medicine (TCM), myrrh (Mo Yao) is commonly paired with frankincense (Ru Xiang, from Boswellia species) in formulas targeting blood stasis, pain, and wound healing.

2.4 African and Arabian Traditions

In traditional African, Arabian, Indian, and Chinese medicine, Commiphora oleogum resins have been used for centuries for the treatment of wounds and fractures, against arthritis, obesity, parasitic infections, various gastrointestinal diseases, and as painkillers. The resin of Commiphora erythraea is traditionally used to protect livestock from ticks and to treat diseases related to inflammation.

2.5 Broad Ethnobotanical Record

Myrrh has been used traditionally for treating wounds, mouth ulcers, aches, fractures, stomach disorders, microbial infections, and inflammatory diseases. It is used as an antiseptic, astringent, anthelmintic, carminative, emmenagogue, and as an expectorant. Traditionally, myrrh has been employed to alleviate various conditions, including wounds, pain, fractures, mouth ulcers, arthritis, gastrointestinal disorders, and infections.

3. Phytochemistry: Key Constituents and Active Compounds

3.1 General Phytochemical Profile

More than 300 phytochemical molecules, such as mono-, sesqui-, di-, and triterpenes, as well as steroids, have been identified in oleogum resins of the genus Commiphora. The chemical composition of myrrh is diverse, including volatile oils, terpenes, steroids, lignans, and other compounds. The composition of myrrh resin is approximately 30%–60% gum (including acidic polysaccharides), 25%–40% resin, and 3%–8% volatile oil (which contains eugenol, herbolene, and many furanosesquiterpenes).

3.2 Furanosesquiterpenoids (Myrrh)

Sesquiterpenoids and furanosesquiterpenoids are of particular interest since they not only account for the characteristic "myrrh" odors but also exhibit antibacterial, antifungal, and antiviral activities. The most studied compounds in this class are:

• Furanodienone — the volatile fraction of Commiphora erythraea is a source of furanosesquiterpenoids, among which furanodienone is the most promising pharmacologically active compound.
• Curzerene, furanoeudesma-1,3-diene, and lindestrene — the analgesic properties of myrrh depend on the presence of bioactive sesquiterpenes with furanodiene skeletons; standardized extracts have been characterized for their curzerene, furanoeudesma-1,3-diene, and lindestrene content.
• 2-Methoxyfuranodiene (CM1) and 2-Acetoxyfuranodiene (CM2) — two furano-sesquiterpenoids isolated from the chloroform fraction of the ethanolic extract of Arabic Commiphora myrrha resin. The mode of antibacterial action of CM-1 and CM-2 has been elucidated by molecular docking with bacterial DNA gyrase; both compounds interact with key residues of DNA gyrase.

Myrrh's composition varies depending on plant origin; for instance, C. myrrha is rich in sesquiterpene lactones.

3.3 Guggulsterones (C. wightii / C. mukul)

Another promising substance group found in Commiphora is phytosteroids — especially guggulsterones — so far exclusively found in C. mukul. Guggulsterone is a naturally occurring plant sterol found in the resin of the guggul tree, Commiphora mukul. This bioactive component exists in two main forms: E-guggulsterone and Z-guggulsterone. The total percentage of guggulsterones ranged from 0.75 to 2.35% in natural gum; in every case, the concentration of the Z isomer was more than twice that of the E isomer.

3.4 Other Constituent Classes

Guggul resin is a mixture of phytoconstituents including volatile oil containing terpenoidal constituents such as monoterpenoids, sesquiterpenoids, diterpenoids, and triterpenoids; steroids; flavonoids; guggultetrols; lignans; sugars; and amino acids. Diterpenes, sesquiterpenes, and monoterpenes have been reported from different Commiphora species; these include dammarane triterpenes from C. dalzielii and C. confusa, and mansumbinones or dammarane triterpenes from C. kua, along with lignans and their epimers from the resins of C. kua and C. erlangeriana.

4. Mechanisms of Action

4.1 FXR Antagonism and Lipid Regulation (Guggulsterones)

Guggulsterones, the presumed bioactive compounds of guggul, may antagonize two nuclear hormone receptors involved in cholesterol metabolism, which is a possible explanation for the hypolipidemic effects of these extracts. More specifically, a primary mechanism involves guggulsterone's role as an antagonist of the farnesoid X receptor (FXR), which regulates bile acid and cholesterol metabolism in the liver. Guggulsterone's direct up-regulation of the bile salt export pump (BSEP) is dominant over its FXR-mediated antagonism and is a plausible mechanism for the hypolipidemic effect; increases in BSEP result in increased bile acid excretion, which may be reflected in lower serum bile acid concentrations.

Guggulsterone can also activate the pregnane X receptor (PXR), a "master switch" that boosts production of detoxification enzymes such as CYP3A. Studies have also found that guggulsterone is a much more potent antagonist for nuclear receptors such as the mineralocorticoid receptor (MR), glucocorticoid receptor (GR), and androgen receptor (AR) than for FXR.

4.2 Anti-Inflammatory Pathways

Guggul exerts anti-inflammatory effects by inhibiting the NF-κB pathway. For myrrh-derived furanosesquiterpenoids, a study found that furanodien-6-one from Commiphora erythraea inhibits NF-κB signaling and attenuates LPS-induced neuroinflammation (as cited in the literature on pharmacological studies of Commiphora species). Beyond FXR and PXR, guggulsterone has been shown in preclinical work to influence inflammatory signaling pathways (for example, NF-κB), apoptosis (programmed cell death), and oxidative stress responses.

4.3 Analgesic Mechanisms

The analgesic properties of myrrh depend on the presence of bioactive sesquiterpenes with furanodiene skeletons. Preclinical data have shown that these sesquiterpenes mediate both central and peripheral analgesic effects: administration of Commiphora molmol extract in doses of 250 and 500 mg/kg increased latency time to thermal stimuli at 30, 60, and 90 minutes post-oral dosage in a dose-dependent manner in mice compared with the control group.

4.4 Antibacterial Mechanisms

The oleo-gum-resin of Commiphora myrrha is one of the most known natural antimicrobial agents, mainly due to its furanosesquiterpenes. At the molecular level, the antibacterial action of CM-1 and CM-2 has been elucidated by molecular docking with bacterial DNA gyrase; both compounds interact with key residues of DNA gyrase.

4.5 Pro-Apoptotic and Anticancer Mechanisms

Guggulsterone induces apoptosis (programmed cell death) by influencing apoptotic markers such as caspases and Bcl-2 family proteins. In the context of furano-sesquiterpenoids from myrrh resin, cell survival assays demonstrated that both 2-methoxyfuranodiene and 2-acetoxyfuranodiene were highly cytotoxic in HepG2 and MCF-7 cells, with IC50 values of 3.6 and 4.4 µM, respectively; both compounds induced apoptosis and caused cell cycle arrest in treated HepG2 cells.

5. Scientific Evidence by Area of Use

5.1 Cardiovascular and Lipid Metabolism (Guggul / C. wightii)

In 1987, guggulipid — the petroleum extract of guggul — was officially recognized in India as a lipid-lowering remedy and is widely used there for this indication. The evidence base, however, is mixed.

Earlier clinical trials (mainly Indian populations): Before 2003, most scientific evidence suggested that guggulipid elicits significant reductions in serum total cholesterol, low-density lipoprotein (LDL), and triglycerides, as well as elevations in high-density lipoprotein (HDL). A randomized double-blind study with 61 hypercholesterolemic patients found that administration of 50 mg of guggulipid or placebo capsules twice daily for 24 weeks resulted in guggulipid decreasing total cholesterol by 11.7%, LDL by 12.5%, triglycerides by 12.0%, and the total cholesterol/HDL ratio by 11.1% from post-diet levels, while levels were unchanged in the placebo group. Additionally, lipid peroxides, indicating oxidative stress, declined 33.3% in the guggulipid group without any decrease in the placebo group.

A 2003 JAMA randomized controlled trial in Western patients: A clinical study exhibited that gugulipid (containing 2.5% guggulsterones) increased the LDL level, but had no impact on the level of cholesterol, HDL, TG, and very-low-density lipoprotein (VLDL) in a Western population.

A 2008 Norwegian RCT: A double-blind, randomised, placebo-controlled trial in Norwegian general practice enrolled 43 women and men aged 27–70 with moderately increased cholesterol, randomised to use 2,160 mg guggul (4 capsules) daily or placebo for 12 weeks. Even if total cholesterol and HDL-C were significantly reduced, the clinical magnitude of this remained obscure.

Meta-analysis (2021): A systematic review of 32 studies with 1,386 participants found randomized controlled trials of Commiphora mukul (guggulu) on hypercholesterolemia. The average intervention duration was 12 weeks. Meta-analysis showed that guggulu reduced total cholesterol by 16.78 mg/dL (95% CI: 13.96 to 2.61; p = 0.02) and LDL by 18.78 mg/dL (95% CI: 34.07 to 3.48; p = 0.02).

Overall evidence strength: The effects of guggulipid in patients with high cholesterol are not clear, with some studies finding cholesterol-lowering effects and other research suggesting no benefits. At this time, there is not enough scientific evidence to support the use of guggul for any medical condition according to some reviewers. Key limitations include differences in studied populations (Indian vs. Western), variable standardization of preparations, and short trial durations. The evidence is currently mixed and insufficient to make definitive clinical recommendations.

5.2 Analgesic and Anti-Inflammatory Effects (Myrrh)

The analgesic and anti-inflammatory properties of myrrh have been demonstrated principally in preclinical (animal) studies, with limited human pilot data.

Preclinical evidence: Studies evaluated the anti-inflammatory and analgesic effects of 85% ethanol extract of Commiphora myrrha and its different solvent fractions. These data demonstrated that the ethanol extract and petroleum ether extract possess analgesic and anti-inflammatory activities, supporting the traditional application of this herb in treating various diseases associated with inflammatory pain.

Human pilot study (MyrLiq®): A balanced sample of 95 female and 89 male volunteers (ages 18 to older than 60) exhibiting different pain pathologies, including headache, fever-dependent pain, joint pain, muscle aches, lower back pain, and menstrual cramps, was divided into two groups. The experimental group received 1 capsule/day containing either 200 mg or 400 mg of MyrLiq® (corresponding to 8 mg and 16 mg of bioactive furanodienes, respectively) for 20 days, while the placebo group was given the same number of capsules with no MyrLiq®. This study provided preliminary signals of analgesic efficacy but was a pilot investigation without high-level controlled methodology. More rigorous randomized controlled trials are needed before clinical conclusions can be drawn.

5.3 Oral Health and Antimicrobial Effects

In the era of evidence-based practice, many clinical and pre-clinical studies have investigated the clinical efficacy of C. myrrha as an oral antimicrobial drug due to its traditional uses. There is a growing amount of evidence from clinical trials suggesting C. myrrha has effective anti-inflammatory and antibacterial properties on oral and dental tissues. Traditional topical application in the mouth has been used for periodontal conditions, mouth ulcers, and infections. However, the available clinical trials in this area are generally small and not always rigorously controlled. Overall, the evidence is promising but remains preliminary.

5.4 Wound Healing

Studies have investigated the antimicrobial, antioxidant, and wound-healing properties of Commiphora myrrha resin extract and its solvent fractions. An in vitro study demonstrated wound closure activity on human dermal fibroblast (HDF) cells treated with crude ethanol extract, with quantitative assessment of scratch wound closure at multiple time points. The existing evidence for wound healing is currently limited to preclinical and in vitro models; no large-scale human clinical trials have been published.

5.5 Anticancer and Cytotoxic Properties

Recent studies have reported a range of effects associated with myrrh and its chemical compounds, including anti-inflammatory, anti-cancer, analgesic, antioxidant, and anti-microbial properties. In vitro work has shown that both 2-methoxyfuranodiene and 2-acetoxyfuranodiene were highly cytotoxic in HepG2 and MCF-7 cells, with IC50 values of 3.6 and 4.4 µM, respectively. For guggulsterones, a systematic review and meta-analysis including 40 preclinical studies found that guggulsterone induces apoptosis in various cancer cell lines and significantly modulates apoptotic markers, highlighting strong preclinical evidence for anticancer potential but noting the absence of human clinical trials.

Evidence strength: All anticancer evidence for Commiphora constituents is currently at the in vitro and animal study level. No human clinical trials have evaluated Commiphora preparations for cancer treatment or prevention.

5.6 Hepatoprotective Effects

Preclinical research has investigated myrrh's potential to protect the liver against toxic insults. A rat model study examined the impacts of C. myrrha (500 mg/kg) alone or in combination with 40% ethanol (3 g/kg), daily for 30 days. The results showed that treatment with C. myrrha after oral consumption of ethanol caused a reduction in serum liver function parameters (alanine transferase, aspartate transaminase, and total bilirubin), hepatic tumor markers, and hepatic lipid peroxidation indicators. This evidence is purely preclinical; no human hepatoprotective trials have been conducted.

5.7 Acne

One small clinical trial found that guggul (Commiphora mukul) compared favorably to tetracycline in the treatment of cystic acne. The amount of guggul extract taken in the trial was 500 mg twice per day. This represents very limited evidence from a single small trial, and further independent replication is needed.

6. Body Systems and Health Areas Associated with Commiphora

• Cardiovascular / lipid metabolism: Guggulsterones from C. wightii/C. mukul have been investigated for dyslipidemia and atherosclerosis risk reduction via FXR antagonism and BSEP upregulation.
• Musculoskeletal / inflammatory: Both myrrh and guggul have traditional and preclinical evidence for use in arthritis, joint pain, and generalized inflammatory conditions via NF-κB inhibition.
• Pain management: Furanodiene-containing myrrh extracts show analgesic activity in preclinical models and a small pilot study.
• Oral and dental health: Topical and rinse applications have been studied for antimicrobial and anti-inflammatory effects on gingival and periodontal tissues.
• Gastrointestinal: Traditionally used as carminative, anthelmintic, and for gastrointestinal infections; modern antimicrobial data partially supports this.
• Dermatological / wound healing: Topical myrrh preparations have a documented ethnobotanical history in wound care, supported by preclinical data.
• Reproductive: Historical use as an emmenagogue, and a clinical trial evaluated myrrh in incomplete abortion (see safety section for relevant findings).
• Oncology (experimental only): Preclinical cytotoxicity and apoptosis-induction data across multiple cancer cell lines; no human data exist.

7. Dosage Forms and Reported Dosages

The following dosages are drawn solely from published study reports and should not be interpreted as recommendations:

• Guggulipid for hypercholesterolemia: 50 mg of guggulipid (in capsules) twice daily for 24 weeks was used in a randomized double-blind trial of 61 patients with hypercholesterolemia.
• Guggul extract (Norwegian RCT): 2,160 mg guggul (4 capsules) daily for 12 weeks was administered to subjects with moderately increased cholesterol.
• Guggulipid for acne: 500 mg of guggul extract twice per day was used in the clinical trial comparing guggul to tetracycline in cystic acne.
• MyrLiq® (C. myrrha extract) for pain: 1 capsule per day containing either 200 mg or 400 mg of MyrLiq® (corresponding to 8 mg and 16 mg of bioactive furanodienes, respectively) for 20 days was used in the pilot analgesic study.
• Myrrh oleo-gum-resin for incomplete abortion: Capsules containing 500 mg of myrrh oleo-gum-resin were administered three times a day for 2 weeks in a randomized double-blinded placebo-controlled trial.
• Commiphora molmol extract for preclinical analgesic/anti-inflammatory testing: Doses of 250 and 500 mg/kg were administered orally to mice in hot-plate tests. (Note: these are animal study doses, not directly translatable to human dosing.)

8. Safety Considerations and Drug Interactions

8.1 Pregnancy and Uterine Stimulation

In ancient traditional Persian manuscripts, it has been noted that myrrh may act as a uterine stimulant and probably cause complete abortion. A clinical study has also reported miscarriage in women who used a large amount of myrrh during pregnancy. Myrrh should be avoided in pregnancy.

8.2 Dermal Sensitization

The essential oil of myrrh can cause skin irritation and allergic dermatitis.

8.3 Gastrointestinal Adverse Effects (Guggul)

Some adverse reactions have been noted in clinical trials of guggulipid, including loose stools, mild nausea, and hiccup. In some clinical studies with guggulipid, hypersensitivity rashes have also been noted.

8.4 Long-Term Safety

No clinical studies have been conducted to evaluate the safety of long-term use of guggul or guggulsterone.

8.5 Drug Interactions via CYP Enzyme Modulation

Z-guggulsterone is a substrate and inducer of CYP3A4. Therefore, the involvement of CYP3A4 in the metabolism presents a major variable for guggul therapy due to its variants, diverse substrates, and altered expression by pathological conditions and co-administered drugs. Guggulsterone may interfere with the metabolism of certain prescription drugs by affecting the liver's CYP3A4 enzyme system, which breaks down many medications. Theoretically, myrrh may have an additive effect with diabetic medications. Myrrh may also act as an antagonist to the anticoagulant effects of warfarin.

8.6 Reproductive Toxicology in Animal Studies

In 3-month animal studies, gum guggul extract (GGE) formulation exposure via oral gavage exhibited the potential to be a reproductive toxicant in male mice, but not in rats, as evidenced by decreased testicular spermatid head counts and a corresponding decrease in testicular weights with increasing dose. The relevance of these findings to humans has not been established.

8.7 Conservation and Supply Concerns

Despite its medicinal potential, Commiphora wightii is classified as critically endangered due to overharvesting and poor natural regeneration. The species has been put in the "Critically Endangered" category by the IUCN. Crude methods used to increase yield of oleo-gum resin cause plant mortality; unscientific tapping methods have been identified as a leading cause of population decline.
