“…It is also a potential topical remedy for skin problems such as eczema, acne, and psoriasis. In addition, the polyacetylene ingredients extracted from the root of burdock also possess potent anti-bacterial and anti-fungal activities (Takasugi et al, 1987).…”

Abstract. Arctium lappa, commonly known as burdock, is being promoted/recommended as a healthy and nutritive food in Chinese societies. Burdock has been used therapeutically in Europe, North America and Asia for hundreds of years. The roots, seeds and leaves of burdock have been investigated in view of its popular uses in Traditional Chinese Medicine (TCM). In this review, the reported therapeutic effects of the active compounds present in the different botanical parts of burdock are summarized. In the root, the active ingredients have been found to "detoxify" blood in TCM term and promote blood circulation to the skin surface, improving the skin quality/texture and curing skin diseases like eczema. Antioxidants and anti-diabetic compounds have also been found in the root. In the seeds, some active compounds possess anti-inflammatory effects, and potent inhibitory effects on the growth of tumors such as the pancreatic carcinoma. In the leaf extract, the active compounds isolated can inhibit the growth of micro-organisms in the oral cavity. The medicinal uses of burdock in treating chronic diseases like cancers, diabetes and AIDS have been reported. However, it is also essential to be aware of the side-effects of burdock including contact dermatitis and other allergic/inflammatory responses that might be evoked by burdock.

“…Most of the aliphatic acetylenes isolated from A. lappa (17,(23)(24)(25)(26)(27)(28)(35)(36)(37)(38) are widely distributed in Asteraceae, whereas the dithiophenes (58-69) isolated from this species are not very common as only a few have been isolated from other plant species et al 1969;Garrod et al 1978;Yates and England 1982;Lund and White 1990;Lund 1992;Degen et al 1999;Hofmann 2003, 2004;Hansen et al 2003 (Continued) 142 Schulte et al 1967;Bohlmann et al 1973;Washino et al 1986a,b;Washino et al 1987;Takasugi et al 1987;Christensen and Lam 1990 Artemisia dracunculus L.

“…As much as 75% of the carbohydrate content in the plant is stored in the root as a complex fructan, gamma-glucoside-fructose ester, known as inulin (Harborne and Herbert, 1993). Burdock seed also contains polyacetylenes (Takasugi et al, 1987) that have antibacterial, antifungal and anti-HIV activity (World Health Organization, 1989;Yao et al, 1992;Takasugi et al, 1987) and tannins.…”

The herbal mixtures, Essiac™ and Flor‐Essence™, are sold as nutritional supplements and used by patients to treat chronic conditions, particularly cancer. Evidence of anticancer activity for the herbal teas is limited to anecdotal reports recorded for some 40 years in Canada. Individual case reports suggest that the tea improves quality of life, alleviates pain, and in some cases, impacts cancer progression among cancer patients. Experimental studies with individual herbs have shown evidence of biological activity including antioxidant, antioestrogenic, immunostimulant, antitumour, and antiocholeretic actions. However, research that demonstrates these positive effects in the experimental setting has not been translated to the clinical arena. Currently, no clinical studies of Essiac™ or Flor‐essence™ are published, but a clinical study is being planned at the British Columbia Cancer Agency by the University of Texas‐Center for Alternative Medicine (UT‐CAM) and Tzu‐Chi Institute for Complementary and Alternative Medicine.
