Guaiac resin has no known or reported irritant or toxicological effects, particularly at levels expected through normal diet. Consumption of significant quantities of isolated guaiac resin may cause gastrointestinal effects.
Very little to no guaiac resin is absorbed following consumption. Residual resin is destroyed in the colon.
