Chop Wah On 華安药行 is a Chinese medicine store at 34 Upper Cross Street, in a Chinatown shophouse, Singapore. It holds a Google rating of 4.5 from 39 reviews.
A good Chinese medicine store is judged on the quality and freshness of its herbs, on whether the staff can explain what each ingredient is used for, and on how clearly it labels its products. Dried herbs keep their aroma best in sealed, dry containers, so it helps to check packaging and ask how long a herb keeps once opened. Many shops of this kind can prepare herbal soups or blends on request, and it is worth asking about any ingredient you are unsure of. Regulars often return to the same staff for advice and keep a list of the herbs their family uses.
Upper Cross Street is one of the old streets of Chinatown, which makes this shop a fitting stop for herbs and advice while exploring the neighbourhood's heritage.
