The efficacy and function of calcined turtle shell
I have been experiencing physical weakness lately, with easy fatigue and frequent insomnia with vivid dreams. I heard that Zhi Guiban (processed turtle shell) has the effect of nourishing yin and subduing yang, which can improve my symptoms. I would like to know what other benefits it may have.

Turtle shell refers to the plastron of a turtle. Through specific processing methods, such as roasting or stir-frying, the shell becomes more easily absorbed by the human body and its therapeutic effects are enhanced. This processing method is called "zhì" (roasting or stir-frying with liquid adjuvants). As a commonly used traditional Chinese medicinal material, processed turtle shell offers the following therapeutic functions and effects:
1. Nourishing yin and subduing yang: It can nourish the yin of the liver and kidney, reduce internal heat, and subdue hyperactive liver yang, thereby calming internal wind. This is particularly effective in treating symptoms such as yin deficiency with yang hyperactivity, yin deficiency with wind movement, and yin deficiency with internal heat, including lumbago and knee pain, dizziness, vertigo, tidal fever with night sweats, and other similar conditions. Especially for menopausal women experiencing symptoms such as night sweats, irritability, and hot flashes, processed turtle shell provides unique regulatory effects.
2. Consolidating essence and stopping seminal emission: For men experiencing seminal emission or premature ejaculation caused by kidney deficiency, processed turtle shell demonstrates a good effect in consolidating essence, helping to stabilize the vital essence and reduce abnormal loss of semen.
3. Nourishing blood and calming the mind: Processed turtle shell is rich in various amino acids, trace elements, and other nutrients, which help nourish the blood and improve neuroasthenic symptoms such as insomnia, forgetfulness, and palpitations.
4. Clearing heat and detoxifying: Due to its cold nature, processed turtle shell also has the effect of clearing heat and detoxifying, and can be used in treating conditions such as yin injury caused by febrile diseases and abscesses accompanied by pain and swelling.
