In Traditional Chinese Medicine (TCM), tortoise plastrons are plants that belong to the 'Tonic herbs for Yin Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Yin tonics have a heavy, moist nature. They either nourish the Kidneys and Liver or moisten the Lungs and Stomach. Extreme Yin Deficiency often translates into a 'burn-out', unfortunately more and more common among people today. It is worth mentioning that another great remedy against Yin Deficiency is a lot of rest and sleep; no herb will ever be able to replace this!
Furthermore tortoise plastrons are plants that are Cool in nature. This means that tortoise plastrons tend to help people who have too much 'Heat' in their body, although with less effect than a plant that would be Cold in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Heat in their body are said to either have a Yang Excess (because Yang is Hot in nature) or a Yin deficiency (Yin is Cold in Nature). Depending on your condition tortoise plastrons can help restore a harmonious balance between Yin and Yang.
Tortoise plastrons also taste Salty and Sweet. 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. Salty ingredients like tortoise plastrons tend to have a draining effect in the body because they clear accumulations, remove Phlegm and soften hard lumps. 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 tortoise plastrons are thought to target the Heart, the Kidney and the Liver. In addition to regulating Blood flow, in TCM the Heart is believed to be the store of the 'Mind' which basically refers to someone's vitality. 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. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and the Body Fluids. It also takes a leading role in balancing our emotions.
