Tianshe Du (Snake Poison), also known as Shetou Ding (Snake-Head Carbuncle), is a condition caused by excessive Heart Fire attacking and accumulating locally. The affected finger swells like a snake's head, presenting with redness, swelling, and pain that may radiate to the heart region. In severe cases, alternating chills and fever occur, with swelling and pain spreading upward. Apply five moxa cones on the apex of the swelling, and apply Xionghuang San (Realgar Powder) topically. Internally administer Chansu Wan (Toad Venom Pill) to induce sweating and resolve toxicity; mild cases gradually subside, suppurative cases rupture with pus discharge, and severe cases result in tissue necrosis. If swelling persists after rupture, insert a Chansu Strip into the wound and cover with an ointment plaster for effective results; for necrotic wounds, apply Yuhong Gao (Jade Red Ointment); for patients with deficiency who fail to heal, concurrently administer tonifying formulas.
