Guggul for hyperlipidemia: A review by the Natural Standard Research Collaboration
ABSTRACT To evaluate the scientific evidence on guggul for hyperlipidemia including expert opinion, folkloric precedent, history, pharmacology, kinetics/dynamics, interactions, adverse effects, toxicology, and dosing.
Electronic searches were conducted in nine databases, 20 additional journals (not indexed in common databases), and bibliographies from 50 selected secondary references. No restrictions were placed on language or quality of publications. All literature collected pertained to efficacy in humans, dosing, precautions, adverse effects, use in pregnancy/lactation, interactions, alteration of laboratory assays, and mechanism of action. Standardized inclusion/exclusion criteria were utilized for selection.
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) [Kotiyal JP, Bisht DB, Singh DS. Double blind cross-over trial of gum guggulu (Commiphora mukul) Fraction A in hypercholesterolemia. J Res Indian Med Yoga Hom 1979;14(2):11-6; Kotiyal JP, Singh DS, Bisht DB.

A comparative study on hypocholesterolaemic effect of allicin, whole germinated seeds of bengal gram and guggulipid of gum gugglu. Phytother Res 2000;14(3):200-02]. However, most published studies were small and methodologically flawed. In August 2003, a well-designed trial reported small significant increases in serum LDL levels associated with the use of guggul compared to placebo [Szapary PO, Wolfe ML, Bloedon LT, et al. Guggulipid for the treatment of hypercholesterolemia: a randomized controlled trial. JAMA 2003;290(6):765-72]. No significant changes in total cholesterol, high-density lipoprotein (HDL), or triglycerides were measured. These results are consistent with two prior published case reports [Das Gupta R. Gugulipid: pro-lipaemic effect. J Assoc Physicians India 1990;38(12):346].
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. Guggul may cause stomach discomfort or allergic rash as well as other serious side effects and interactions. It should be avoided in pregnant or breast-feeding women and in children. Safety of use beyond 4 months has not been well studied.

- "Traditional (India) uses of C. mukul (CM) are for its anti-inflammatory, antispasmodic, carminative , emmenagogue, hypoglycemic, alternative , antiseptic, and astringent, a thyroid stimulant, anthelminitic, antihyperlipidemia , antidiabetic and antioxidant properties (Ramesh et al., 2011). It is an important herb used in the treatment of several degenerative disorders in modern medicine too and established as a hypolipidemic drugs (Ulbricht et al., 2005). Ayurvedic medicines containing gum guggul often contain guggul in their names, such as in Shunthiguggul , and Yogaraja guggul. "
ABSTRACT: The purpose of this study was to investigate the effects of Commiphora mukul gum resin ethanolic extract (CMEEt) administration against altered activities of key enzymes of carbohydrate metabolism, lipid metabolism and changes in glycogen content (liver and muscle) and lipids (liver and heart) in streptozotocin (STZ) induced insulin deficient diabetic Wistar albino rats. Diabetes was induced by intraperitoneal injection of STZ (55 mg/kg body wt) to male Wistar rats. The animals were divided into four groups: Control (C), control-treated (C+CM), diabetic (D) and diabetic-treated group (D+CM). Diabetic-treated and control-treated rats were treated with C. mukul gum resin ethanolic extract (CMEEt) in 2 ml distilled water, orally (200 mg/kg body weight/day for 60 days). At the end of the experimental period, biochemical parameters related to carbohydrate and lipid metabolism were assayed. The significant enhancement in tissue lipids (heart and liver) total cholesterol, triglycerides, phospholipids and free fatty acids of diabetic rats were nearer to normalized in diabetic treated rats (D+CM). Alterations in the activities of enzymes of glucose metabolism (hexokinase, phosphofructokinase, pyruvate kinase, and glucose-6-phosphatase, fructose-1,6-bisphosphatase and glucose-6- phosphate dehydrogenase) and lipid metabolism (fatty acid synthase, malic enzyme and lipoprotein lipase) as observed in diabetic (D) rats were prevented with CMEEt administration. In conclusion, our findings indicate improvement of glucose and lipid metabolisms in STZ induced diabetic rats by treatment with Commiphora mukul and suggest that the plant can be used as an adjuvant for the prevention and/or management of insulin deficiency and disorder related to it.

ABSTRACT: Oleo gum resin secreted by Commiphora mukul, also known as gum guggul, has been used widely as an ayurvedic drug. Commiphora mukul is a short thorny shrub that is native to the Indian subcontinent. Oleo gum resin extracted by incision of the bark is a very complex mixture of gum, minerals, essential oils, terpenes, sterols, ferrulates, flavanones and sterones. Its active constituents, the Z- and E-guggulsterones, have been demonstrated to exhibit their biological activities by binding to nuclear receptors and modulating the expression of proteins involved in carcinogenic activities. Guggulsterones have also been reported to regulate gene expression by exhibiting control over other molecular targets including transcription factors such as nuclear factor (NF)-κB, signal transducer and activator of transcription (STAT) and steroid receptors. Considerable scientific evidence indicates the use of gum guggul as a therapeutic agent in the treatment of inflammation, nervous disorders, hyperlipidaemia and associated cardiac disorders such as hypertension and ischaemia, skin disorders, cancer and urinary disorders. This review highlights the taxonomic details, phytochemical properties and pharmacological profile of gum guggul.

Myrrh is also used as a healing tonic, as a stimulant and as a hypolipidemic agent (Urizar et al. 2002; Wu et al. 2002; Ulbright et al. 2005). Traditionally , myrrh is used for the common cold, to relieve nasal congestion and coughing. "
ABSTRACT: Commiphora wightii (Arn.) Bhandari syn. C. mukul Engl. (Burseraceae) is an economically and pharmacologically important slow growing, dioecious, balsamiferous woody, multipurpose shrub heading towards extinction. Commonly known as “Guggul” due to the presence of steroidal compound guggulsterone in the oleo-gum resin, it has been used in treating various ailments and disorders since ancient times (2000 B.C.). Evaluation and confirmation of hypolipidemic effects of guggul based on Ayurvedic text in 1960s provided a new insight into its pharmacological applications. Two bioactive isomers of guggulsterone, E and Z, are responsible for lipid- and cholesterol-lowering activities. Recently, it has been shown to have anti-cancerous activity also. It is found in the dry regions of Indian subcontinent, namely India, Pakistan and Bangladesh. Ruthless and unscientific harvesting of oleo-gum resin from the wild, by local populations, for economic benefits with negligible conservation efforts has made this species endangered and has led to its inclusion in Red Data Book of IUCN. Although this plant has many excellent traits, adequate attention has not been focused on its conservation and improvement. Conventional propagation methods i.e., seeds, cuttings and air layering are in place but have many limitations. Therefore, application of modern biotechnological tools needs to be standardized for harnessing maximum benefits from this pharmaceutically important plant. An efficient regeneration system needs to be in place for improvement of this genus through genetic transformation and production of useful metabolites in cell cultures. Studies are in progress for micropropagation through shoot multiplication and somatic embryogenesis, as well as for secondary metabolite (guggulsterone) production in callus cultures and bioreactors. No selected germplasm is available for C. wightii since it is a wild plant. Breeding programs have not yet been started due to lack of systematic cultivation and conservation programs. Moreover, little information has been gathered regarding the genetic variability in this species using RAPD and ISSR markers. No details are available about genetic makeup and QTL linkage maps. Investigations are in progress to search sex linked markers in this dioecious species. Research is also in progress to decipher the molecular mechanisms underlying various pharmacological actions of guggul. Since the approval of use of guggul as a food supplement by United States Food and Drug Administration in 1994, an exponential increase in research publications on various aspects of research on guggul have been published. Present communication summarizes the problems, progress made and suggests some future directions of research for this important endangered medicinal plant.Genetic Resources and Crop Evolution 08/2012; 59(6).
