Dr. Zhang practiced as an MD in Shanghai. In the US he practices as an herbalist. In China MDs pactice both western and eastern medicine. Dr. Zhang will feel to your pulse, look at your tongue before prescribing your herbal remedy. The guys in the herbal store will compile your herbs which is interersting to watch. Dr. Zhang is really a terrific herbalist. I’ve heard him on the phone with other medical doctors discussing a patient’s illness. He speaks Mandarin and English. Call and ask when Dr. Zhang will be in — he’s off on Wednesdays and takes a break sometime during the day.
