Hi Siew Ping,
When you're looking for a TCM physician in Singapore, there are a few things that you should take note of.
Firstly, you should find out if the physician is registered with the TCM Practitioners Board (TCMPB), a statutory board under the charge of Ministry of Health (MOH). If you are at his/her clinic, you should ask to see the physician’s registration certificate. Most of the times, the certificate will be hanging on the clinic's wall.
Here's a sample certificate:
Alternatively, you may visit the official website at www.tcmpb.gov.sg to verify his/her status.
Secondly, you may want to consider the physician’s academic qualifications, area of interest, years of experience and recommendations through online forums or by word of mouth. I believe that all TCM physicians are proficient and competent in their areas of specialty. The best physician should be one who is able to address your concerns.
