Guest guest Posted August 31, 2005 Report Share Posted August 31, 2005 Hi folks, So which solvent(s) will successfully extract allantoin from comfrey? Just alcohol? I've been learning about water, alcohol, vinegar, oil, and glycerin extractions, and mixtures made from various combinations of those. Unfortunately it's not so easy to find out which are good for what purposes <laugh> -Josh Quote Link to comment Share on other sites More sharing options...
