Way back in 1941, Dr. Ho Kai Cheong, trained in China’s Canton Wah Lam Natinoal Physician’s School, formulated a unique concoction of 21 specially chosen herbs. This famous Ho Yan Hor® herbal tea is now widely known and has been trusted for generations. Ho Yan Hor® now introduces a new formula, Night Tea is all-natural, without any trace of preservatives, artificial flavoring and coloring. It is suitable for drinking at night as it will not affect sleep.
