This traditional Chinese ointment is called Si Huang Gao (Four Yellows Ointment) in Chinese. This is because all four of the Chinese names of its ingredients contain the word huang or yellow.

These four ingredients, Huang Lian, Huang Qin, Huang Bai, and Da Huang are all bitter and cold in flavor and nature and clear heat and drain fire in function.

Si Huang Gao is an old and famous Chinese herbal topical application for the treatment of hot toxic skin lesions.

Functions:
Clears heat and resolves toxins, disperses swelling and stops pain

Ingredients:
Sesame oil
Beeswax
Huang Lian (Rhizoma Coptidis)
Huang Qin (Radix Scutellariae)
Da Huang (Radix Et Rhizoma Rhei)
Huang Bai (Cortex Phellodendri)

Contraindications:
Do not use for wet, weeping skin lesions, such as poison ivy and impetigo. In that case, oil-based external applications are generally contraindicated since they trap and increase damp turbid evils.

Use:
Apply to non-weeping, red, raised, hot-to-the-touch skin lesions several times per day, covering if necessary with a dressing.
