NOTE: This product was manufactured and analyzed following the instruction of Chinese pharmacopoeia (Edit 2005). But this does not not mean that it could be directly applied to pharmaceutical purpose. It should still be further processed. So this product could only be regarded as raw materials, or intermediates, or as pharmaceutical chemicals.
Also this product is not sterilized, although almost all of the items that analyzed meet the requirement ofChinese pharmacopoeia (Edit 2005). Several steps are still required to deliminate contamination of microorganisms and endotoxin before it could be applied to pharmaceutical purpose.
