Leong Kee (Klang) Bak Kut Teh (Closed)

this bak kut teh is herbal taste, they add a herb that when we eat, we got a headache, it is peppery and strong plunge, if you are not used to herbal bak kut teh, this may not be the one for you, we are wondering what herbs they add into this bak kut teh, we do not enjoy the whole meal, we have a headache everytime we drank the soup, really odd experience we have,you can go try and see if you have this problem as me.
