Hai Tong Pi (Erythrina variegata bark), known in Traditional Chinese Medicine (TCM) as Hǎi Tóng Pí (海桐皮), is the dried bark of a traditional herb long valued in folk practice as a wind-dispelling, dampness-draining, and channel-clearing botanical. Also called Coral Tree Bark, it has been prized for centuries for its ability to relax tendons, ease joint stiffness, and support smooth movement of the limbs. Its nature is bitter, acrid, and neutral, making it a focused yet balanced herb for addressing wind-damp patterns in the channels and collaterals.

Quality & Sensory

Each batch is carefully sun-dried to preserve its natural grayish-brown outer bark and pale inner surface, with a firm, fibrous texture that breaks cleanly when bent. The dried bark carries a mild, earthy, slightly woody aroma. When decocted, it yields a gentle, subtly bitter infusion with a faint acrid note, releasing its character slowly into the brew.
