Lysimachia 3 is based on a traditional prescription (Sanjin Tang, the Three Golds Decoction, referring to Jin Qian Cao, Hai Jin Sha, and Ji Nei Jin) for preventing, reducing, and eliminating stones. Lysimachia, the common name for Jin Qian Cao, refers to several genera of herbs that are reputed to have this stone-resolving effect, including Lysimachia, Glechoma, and Desmodium (the former is used here). Lygodium spore is a very slippery material which, like talc (the slippery stone) is thought to make stones and gravel also slippery (preventing new material from binding onto its surface, thus slipping out more easily). Gallus (chicken gizzard lining) is used both as a digestive aid and to resolve masses (see Gallus-Malt Tablets).
