Poisoning accident by sarin occurred on June 27, 1994, in Matsumoto City of Nagano Prefecture. A visible damage was observed clearly in the plants at the accident site. Brown spotted damage spread from the circumference to center in the leaf of Houttuynia cordata Thunberg. Observation of injured leaf H. cordata and analysis of chemical substances extracted with water from the leaf were carried out in order to clear up the causes of the damage. Also, leaves were exposed to hydrogen fluoride and comparative examination was carried out.<BR>The result showed that H. cordata was damaged with gases of halogen compounds, and F- was detected in the water extract of injured leaves, so, cause substance was estimated to be hydrogen fluoride.
