Rating (out of 5): 2

Burdock (Arctium lappa) has been used in traditional herbal medicine, particularly in Western herbalism and Traditional Chinese Medicine, to "purify the blood" and support the lymphatic system. Historically, herbalists believed that burdock root could help the body clear toxins via support of both the liver and lymphatic drainage pathways. This belief was based on burdock’s reputed diuretic and mild alterative (blood-purifying) properties, and its use for skin conditions like eczema and acne, which were thought to be linked to lymphatic stagnation or toxin buildup.

However, scientific studies specifically assessing burdock’s effects on the human lymphatic system are lacking. Some laboratory and animal studies suggest that burdock may have anti-inflammatory, antioxidant, and hepatoprotective effects, but these do not directly validate its benefit for lymphatic health in humans. The continued use of burdock for lymphatic support in herbal traditions is therefore based on historical practice and anecdotal evidence rather than robust clinical research.

In summary, burdock’s reputation as a lymphatic system supporter is justified by tradition rather than scientific validation. Caution is warranted since scientific evidence for this specific use is minimal, and more research would be needed to substantiate any such claims.
