Bitter Apricot Seed
A potent respiratory herb from ancient China — Bitter Apricot Seed stops cough, calms wheezing, and moistens the intestines with its unique descending action on the Lung Qi.
What Is Bitter Apricot Seed?
Bitter Apricot Seed (Ku Xing Ren, 苦杏仁) is one of the most important respiratory herbs in Traditional Chinese Medicine, derived from the kernels of the bitter apricot (Prunus armeniaca). Unlike its sweet counterpart (Tian Xing Ren), Ku Xing Ren is specifically medicinal — potent in action and used in carefully measured quantities to treat cough, asthma, and constipation.
Bitter and slightly warm in nature, with mild toxicity that is neutralised through proper preparation, Ku Xing Ren descends and disperses Lung Qi — the downward, moistening direction that the Lung naturally governs. This makes it the primary herb for any cough or respiratory difficulty, whether caused by Wind-Cold, Wind-Heat, Dryness, or phlegm obstruction. Its secondary action on the Large Intestine also makes it effective for dry, difficult bowel movements.
History & Origin
Apricot seeds have been recorded as medicinal ingredients in China since antiquity, with Bitter Apricot Seed formally documented as a key respiratory herb across classical texts spanning 2,000 years.
Traditional Uses

Moistens the Intestines
As an oily seed, Ku Xing Ren lubricates the Large Intestine, used for dry constipation where insufficient fluid makes elimination difficult.

Combined with warming herbs like Ephedra and Cassia Bark for cough and panting from external Wind-Cold invasion.
Relieves Wind-Heat Cough
