Eden makes a barley malt sold in the baking isle of US grocery stores (some, like whole foods). otherwise, beer and wine making stores may have some. Vervain needs to be ordered from a herb outlet (internet), organic if possible. as far as doing too much and feeling terrible... that is why i generally just let the doctrine do its thing, and not mess around, unless i suspect that i might be figuring something new out, something not already covered.
