Agave Cautions

Side Effect: "Constant use of the root for arthritis may interfere with some intestinal

   absorption;   so don�t use for more than a week at a time. The fresh tincture may

   be irritating to the skin and mouth of a few individuals; so, if in doubt, put some

   on the inner wrist. If it inflames, don�t use it; use the dry leaf instead, for tea".
