Can Tibetan tour groups buy Tibetan medicine?

Tibetan medicine can't be bought by Tibetan tour groups. Tibetan medicine is sold in many places in Tibet. The tour guide advised you not to buy this Tibetan medicine, otherwise you will only regret it. Because many college students who go to Tibet want to buy something good for their elders and honor them, dirty medicine is one of their best choices. But many Tibetan medicines in Tibet are fake and shoddy. Most of the Tibetan medicine here is imported from Yiwu, which is very cheap, and then sold as local Tibetan medicine at a high price. So you can't buy it.
