Common accompanying symptoms include a sticky and itchy scrotum, short and dark urine, bitter taste in the mouth, and sticky, unsatisfactory bowel movements. Patients may take medications such as Er Miao Wan, Si Miao Wan, Long Dan Xie Gan Wan, Ba Zheng Granules, and Sophora Flavescens Capsules as directed by a physician.

It is suitable for conditions dominated by damp-heat in the lower jiao, accompanied by scrotal dampness, weakness of the lower limbs, and difficult urination. It is especially suitable for bi syndrome caused by downward invasion of damp-heat.
3. Long Dan Xie Gan Wan
Long Dan Xie Gan Wan contains ingredients such as Gentiana, Bupleurum, Scutellaria, Gardenia, and others, and functions to clear heat and drain dampness from the liver and gallbladder. Gentiana clears excessive fire from the liver and gallbladder and eliminates damp-heat in the lower jiao. Scutellaria and Gardenia clear heat, drain fire, dry dampness, and detoxify.

5. Ku Shen Jiao Nang
Ku Shen Jiao Nang's main ingredient is Sophora flavescens, which functions to clear heat, dry dampness, and kill parasites. Sophora flavescens is bitter and cold in nature, and enters the heart, liver, stomach, large intestine, and bladder meridians.
