I'm looking for a place to buy herbal medicine.

My family is about to run out of the Chinese herbal medicine that was prescribed in Japan.
There are means to mail them from Japan, but since I will be using them on a daily basis until my constitution improves,
I would like to be able to purchase them in the vicinity if possible.
I think Chinese medicine is not something special and is commonly used in Japan.
If you know where I can buy Chinese medicine, please let me know.
Thank you very much.
