In Traditional Chinese Medicine (TCM), praying mantis egg-cases 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 praying mantis egg-cases are plants that are Neutral in nature. This means that praying mantis egg-cases 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 praying mantis egg-cases means that you don't have to worry about that!
Praying Mantis Egg-Cases also taste Salty 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. Salty ingredients like praying mantis egg-cases 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 praying mantis egg-cases are thought to target the Kidney and the Liver. According to TCM, 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 on the other hand is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions.
