chinese/herbal treatments

Hi,

Are there any practitioners in Brussels selling herbal medicines?

I'm congested and I'm done with my antibiotic and steroid nasal spray prescribed by the doctor, but still not able to fully drain my sinuses. In the past I tried chinese herbs which got rid of the phlegm, but don't know of any practitioners in the Brussels area.

Can anybody recommend a practitioner who uses/sells herbal medicines?

thanks!
