Inquiry corner

I bought a box of antihypertensive drugs to help me at the Dau Giay market stall in Thong Nhat Dong district. When I used it, I could see the inside of the capsule when I saw that there was a slightly dark brown powder, which smelled of herbs and tasted rough. Meanwhile people say that the powder must have a pale color to be the real medicine. May I ask that? Where to buy is the nearest place where I am staying. Thank you.
