Guest guest Posted May 2, 2004 Report Share Posted May 2, 2004 Alon, In China, I don't know anyone. In Europe, I know that Herbasin (Germany), Plantasia (Austria), ChinaMedica (Germany), Complemedis (formerly Sinecura; Switzerland) and ourselves (LIAN Chinaherb (Switzerland) does that. In America, I don't know. However, if you are not forced by the government, pretty much nobody will do it; it is simply too expensive. Also, most granule companies do testing but, like I said in my last mail, with non-relevant limits. Simon _____ Von: Alon Marcus [alonmarcus] Gesendet: Samstag, 1.

Yes, Sheng Chang checks, but the limit is most of the time 100ppm for the sum of the heavy metals. This means, they do not differentiate them. The limit for mercury lies in most countries at around 0.1ppm. Thus 100ppm (or even 20ppm, which sometimes is done) simply does not cut it. Even for lead, a sensible limit is 10ppm. Hence, 20ppm or 100ppm is completely useless in my opinion. >>>>>Simon, do you know how many companies do these when they sell raw herbs Alon Quote Link to comment Share on other sites More sharing options...
