How does the traditional use of A. canadensis contrast with TCM milkvetch use?

Answer

Focused on external applications and localized relief.

The traditional medicinal applications documented for native North American milkvetches, specifically *Astragalus canadensis*, diverged significantly from the well-established TCM practices involving *A. membranaceus*. While TCM focused heavily on systemic support, such as bolstering the immune system and addressing chronic weakness internally, the North American approach often emphasized external, localized symptom management. This included topical application as a poultice to soothe skin afflictions and sores, suggesting an immediate, symptomatic intervention rather than the long-term, foundational tonic approach favored in Asian traditional medicine.
