Is the Chinese herbal medicine "Zao Jia" the same as soap pod?
Generally speaking, Chinese herbal "Zaojia" and "Zaoyuan" refer to the same plant species—both are names for the fruit of the Gleditsia sinensis tree, a member of the legume family. The details are as follows:
The fruit of the Gleditsia tree, known as Zaojia or Zaoyuan, has various uses. In ancient times, it was commonly used as a detergent because the saponins contained in the fruit have excellent cleaning properties. Additionally, Zaojia possesses certain medicinal values and is believed to help expel phlegm, open the orifices, dissolve nodules, and reduce swelling, making it useful in treating various diseases. In modern times, with advances in technology, traditional applications have declined, but some of its active medicinal components are still extracted for use in pharmaceuticals or health supplements.
Zaojia is slightly toxic; therefore, dosage must be strictly controlled and used only under medical supervision. Do not adjust the dosage or use it excessively or over a prolonged period on your own, to avoid adverse reactions.
