Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Arabinogalactans are polysaccharides derived primarily from the larch tree (Larix species) and have a history of use in traditional herbal medicine, particularly in North America and Siberia. Traditionally, larch arabinogalactan has been used as an immune system modulator and for general wellness, which has led to its inclusion in modern supplements purported to support lymphatic health. The lymphatic system is closely tied to immune function, so ingredients supporting immunity are often associated with lymphatic health by extension.

Scientific studies on arabinogalactans focus mainly on their prebiotic properties and their ability to modulate immune responses, such as enhancing natural killer (NK) cell activity and increasing the production of certain cytokines. However, direct evidence regarding their impact on lymphatic drainage, lymph flow, or specific lymphatic health parameters is lacking. Most claims about lymphatic support are extrapolated from these general immunomodulatory effects rather than from targeted studies on the lymphatic system itself.

Therefore, while arabinogalactans are traditionally used for immune and general wellness, and there is some scientific support for immune modulation, there is limited scientific validation specifically for lymphatic system support. The evidence for their use in this context is mainly traditional, with an evidence rating of 2 due to the indirect nature of supporting data.
