Cordydalis yanhusuo herb no longer banned in Singapore after more than 2 decades
Traditional Chinese medicine (TCM) containing tetrahydropalmatine (THP) and the Corydalis yanhusuo herb has been banned since 1995, but come 1 Jun, the ban will be lifted.
Import and sale of such medicines will then be allowed in Singapore after a Health Sciences Authority (HSA) review.
A THPP dose limit of 19mg a day and additional labelling requirements will also be imposed.
THP is generally used to relieve menstrual cramps and headaches as it activates blood and moving energy flow.
It is naturally present in some herbs, with the Corydalis yanhusuo the most commonly used in TCM.
The ban was incurred after news overseas that it could cause toxicity in liver when consumed.
Lifting the ban was thus done after a HSA review and expert panel study, as well as feedback from the Singapore Chinese Medicines and Health Products Merchant Association.
No major safety concerns were revealed during the reviews should the herbs be used appropriately.
Certain studies, however, still showed high levels of THP can be associated with liver toxicity. As such, the daily limit of 19mg was set in place.
People with liver disease should also avoid medicines or herbs with THP.
