"One of the old medical shops with history that is still around. Chinese Sinseh or Physician is a nice and humble man. Very experienced. Went down to buy some medical herbs based on prescription. Overall, the staff is polite and helpful. The place is especially busy during weekends. "
"My son was on western meds for almost 3 months but didn’t feel any better. Was always in Low grade fever until I met Sinseh Ong. Within a few days the fever subside and my son become active. Thank you so much!"
"Have always been a loyal customer for many years, everyone there is very friendly and helpful, physician is very professional as well. The medicine prescribed always works for my family and me, highly recommended!"
"Randomly found this TCM from some eczema forum, read lots of reviews on eczema patients seeing results and it gave me a glimpse of hope. My 1yo baby had eczema since 3mo, started with small patch on his face, brought him to skin specialist, given steroids. Worked initially but it never cleared. KKH dermatology gave Elidel and Starquis because I was against steroids. Decided to stop steroids when he was about 6mo, his eczema flared, worse than before. Broken skin weeping on his face, bloody clothes and bedsheets every morning. Sleepless nights for everyone. Went to see Dr Ong in the morning, went back home with herbal wash, cream and medicine in liquid and pill form. On the night itself, I've seen a drastic difference on my baby. Itching almost gone, redness calmed down, wounds closing and drying up. It was too good to be true, for the 1st time in months, we both slept well. 2 weeks in, his skin has never been smoother. He's almost 80% cleared, sleeping through the night and mood has never been better. There's always light at the end of the tunnel, we're really thankful for Dr Ong's herbs that helped us regain back normal life."
We visited on 1st Jan 2026 to seek treatment for our mum’s knee pain, and we are truly grateful for the care we received from Mevis and her parents. From the moment we arrived, they were patient, attentive, and genuinely caring. Mevis took the time to carefully assess our mum’s condition, explained the treatment clearly, and made sure she was comfortable throughout. Her parents were equally warm and experienced, offering reassuring advice and sharing their expertise with sincerity. What stood out most was how thoughtful and detailed the consultation was — they didn’t rush, and they treated our mum with kindness and respect, which meant a lot to our family. After the treatment, our mum felt relief and could stand and walk without much pain and was much more at ease. It’s rare to find a TCM clinic that combines experience, professionalism, and genuine compassion so well. We highly recommend Mevis and her parents to anyone looking for trustworthy and effective TCM treatment, especially for joint or knee pain. Thank you for taking such good care of our mum!
"My wife and I went to see if they had the old mountain ginseng roots ends and they had a lot of stock of good quality. The Proprietor of the outlet came out of his shop to speak with my wife as she was in a wheelchair and could not enter. Upon learning that she was undergoing immunotherapy for cervical cancer and had been suffering from water retention in the legs he gave us medicine for it, he is very kind and caring." This was our very first visit to his outlet we did not even know him but his heartwarming gesture told us we will be coming back to give him business again soon. There are many promotional items that made economical sense to get here… many essential items were on like “buy 2 free 1” or “buy 3 free 1”. Heart before business …. Both my wife and I gave four thumbs up for this business👍👍👍👍
