Derived from a leguminous plant, Astragalus Membranaceus (Huang Qi) is sweet and warm, entering the spleen and lung meridians. Classical texts attribute to it the abilities to tonify central Qi, lift Yang, fortify the exterior, expel toxins while promoting tissue regeneration, and support water metabolism to reduce edema. Listed among superior herbs, Astragalus boasts a dense, resilient structure; while its Qi-tonifying strength is slightly milder than that of ginseng, its capacity to uplift and mobilize Qi is especially valued. This is why beauty formulations often favor Astragalus over ginseng or codonopsis.
