Key TCM concepts behind biota seeds (Bo Zi Ren)'s properties
In Traditional Chinese Medicine (TCM), biota seeds 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 biota seeds are plants that are Neutral in nature. This means that biota seeds typically don't affect the balance in your body. Balance between Yin and Yang is a key health concept in TCM. Eating too many "Hot" (Yang) ingredients can lead to an imbalance whereby one has a Yang excess. The inverse is true as well: too many "Cold" (Yin) ingredients can lead to a Yin excess. The Neutral nature of biota seeds means that you don't have to worry about that!
Biota seeds also taste 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. Sweet ingredients like biota seeds 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 biota seeds are thought to target the Heart, the Kidney and the Large intestine. In addition to regulating blood flow, in TCM the Heart is believed to be the store of the "spirit" 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 Large Intestine receives the "impure" parts of the digested food from the Small Intestine, absorbs the remaining fluids and excrete the remainder as feces.
