Rating (out of 5): 2

Nettle (Urtica dioica), particularly in its mixed or whole-plant forms, has a long history of use in traditional herbal medicine systems to support the lymphatic system. Folk and herbal traditions, especially in Europe and North America, have considered nettle as a "blood purifier" and have used it to promote the clearance of waste products via the lymphatic and urinary systems. The rationale is based on its diuretic properties and its presumed ability to stimulate the movement of lymph, reducing congestion and inflammation.

However, scientific studies directly investigating nettle’s effects on the lymphatic system are limited. Most modern research focuses on its anti-inflammatory, antioxidant, and diuretic effects, which could have indirect benefits for lymphatic function but do not provide direct evidence of lymphatic support. The traditional use is supported by anecdotal and empirical evidence from herbalists and historical texts, but lacks significant clinical validation.

Therefore, while nettle is commonly used in traditional contexts for lymphatic health, the evidence for its efficacy is primarily historical and traditional rather than scientific. The strength of evidence is modest, and anyone interested in using nettle for lymphatic support should be aware of the limited direct research in this area.
