Yu Li Ren(郁李仁), also known as Dwarf Flowering Cherry Seed or Pruni Semen in Latin, is a traditional Chinese medicine derived from the seeds of the Prunus humilis, Prunus japonica, and Prunus pedunculata plants. Think of it like the almond of a tiny cherry – it’s the seed inside the fruit that holds the medicinal power.
Primarily grown in Northeast China, Hebei, and Shandong provinces, Yu Li Ren has been used for centuries to address various health concerns.
What is Yu Li Ren Made Of?
Yu Li Ren contains a variety of compounds that contribute to its medicinal properties. These include12:
- Amygdalin: A naturally occurring compound that can be converted into cyanide in the body. Don’t worry, the amount in this herb is generally considered safe when used as directed, but we’ll talk more about safety later.
- Fatty oils: These oils contribute to the seed’s lubricating and laxative effects.
- Volatile organic acids: These contribute to the characteristic aroma and may have other health benefits.
