Does anyone know how long you can store powdered San Pedro before it begins to lose potency? SWIM has a cutting they've had in a closet for a week or so, and they want to dry it out and powder it this weekend. However, they aren't actually planning on using it until a week later.
You have no problem. Keep it dry, dark, and reasonably cool in a sealed container and you would have no problem for many weeks if not months. If you have dried it reasonably well, that is...
i've had some dried peruvian for almost a year now and its still fine, follow advice as in previous post though
