Ma huang has been abused and therefor is not available.
Fyi: according to the most recent ruling by the fda (feb 11, 2004: 21 cfr part 119, pp 27-28), ephedra-mahuang is legal for use by licensed asian medicine practitioners, as long as the herb is not being prescribed a) alone (not with any other herbs), or b) for the purpose of inducing weight loss. i urge you to contact your local fda rep to verify this for yourself. there is no substitute for mahuang; fortunately, rumors of banning the substance are entirely false.
