In Traditional Chinese Medicine (TCM), psoralea fruits are plants that belong to the 'Tonic herbs for Yang Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Yang Tonics are generally used in combination with a small amount of Yin tonics. If Yin is deficient, neither Qi nor Yang herbs alone will be effective. The most common symptoms associated with Yang Deficiency are low libido and impotence. It is worth mentioning that another very effective remedy against Yang Deficiency is regular exercise.
Furthermore psoralea fruits are plants that are Warm in nature. This means that psoralea fruits 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 psoralea fruits can help restore a harmonious balance between Yin and Yang.
Psoralea fruits also taste Bitter and Pungent. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Bitter ingredients like psoralea fruits tend to have a cleansing action on the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. On the other hand Pungent ingredients tend to promote the circulations of Qi and Body Fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such psoralea fruits are thought to target the Spleen and the Kidney. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. 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.
