Wikipedia definition
2. Seiroganis a pharmaceutical drug marketed in Japan, sold as a treatment of the digestive tract (especially as an antidiarrhoeal), whose main active ingredient is "wood creosote" (also wood-tar creosote, or beechwood creosote). The name is nominally a registered trademark of Taiko Pharmaceutical based in Suita, Osaka which is still the major market-share holder, but the enforceability of the tradename has been voided by the Supreme Court of Japan, which ruled seirogan to be a common generic name.
