Ryukakusan Throat Refreshing Candy doesn't contain No doping substances, Higenamin.


Dear Customer,

We thank you very much for your business with us.


Recently misleading information about our products is spreading through Internet.

According to this, our Ryukakusan Throat Refreshing Candy contains prohibited ingredients, Higenamine (a.k.a. Norcoclaurine).   Higenamin is one of the list of substances that will be banned beginning on Jan. 1, 2017 by The World Anti-Doping Agency. 

However, Ryukakusan Throat Refreshing Candy has no Higenamine at all.


As a pharmaceutical company specialized for throat, Ryukakusan will continue to strive providing the better quality  products and service as well as the providing the correct information。


Best regards,
