Common TCM formulas in which palmleaf raspberries are used*:
In Traditional Chinese Medicine (TCM), palmleaf raspberries are plants that belong to the 'Herbs that stabilize and bind' category. This category of herbs is used for treating abnormal discharges and displacement of organs. This includes conditions such as diarrhea, discharges from the vagina, penis or rectum as well as prolapse of the uterus or rectum. It is important to note that herbs in this category only treat symptoms, so one should also use herbs to treat the underlying Deficiency.
Furthermore palmleaf raspberries are plants that are Warm in nature. This means that palmleaf raspberries tend to help people who have too much "cold" in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much cold in their body are said to either have a Yin excess (because Yin is Cold in nature) or a Yang deficiency (Yang is Hot in Nature). Depending on your condition palmleaf raspberries can help restore a harmonious balance between Yin and Yang.
Palmleaf raspberries also taste Sour and Sweet. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Sour ingredients like palmleaf raspberries help with digestion and restrain abnormal discharges of fluids from the body, such as diarrhea or heavy sweating. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what organs and meridians they target. As such palmleaf raspberries are thought to target the Bladder and the Kidney. In TCM the impure water collected by the Kidneys that cannot be used by the body is sent to the Bladder for storage and excretion as urine. The Kidneys do not only regulate the urinary system but also play a key role in the reproductive system and the growth and aging process of the body.
