In Traditional Chinese Medicine (TCM), pearls are plants that belong to the 'Herbs that nourish the Heart and calm the Spirit' category. These herbs are substances that tranquilize the Mind and treat symptoms such as restlessness, palpitations, anxiety or insomnia. They tend to have sedative properties by tonifying Heart Yin and Blood as in TCM it is believed that the Heart is the store of the Mind.
Furthermore pearls are plants that are Cold in nature. This means that pearls typically help people who have too much 'Heat' in their body. 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 pearls can help restore a harmonious balance between Yin and Yang.
Pearls 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 pearls 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 pearls are thought to target the Heart 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 Liver on the other hand 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.
