I am now doing my research that study about Centella Asiatica. I would like to formulate it in the pharmaceutical preparation. Therefore I would like to buy the Centella Asiatica Extract powder that contain Asiaticoside and Madecassoside = 90%. I would like to get it around 100 grams to 250 grams depend on the price. Would you tell me how much for 100g, 150g, 200g, 250g?
I look forward to hearing from you.
