Overview of the efficacy and functions of calcined Cassia

Calcined Cassia is a medicinal material commonly used in traditional Chinese medicine to calm the liver, subdue yang, improve eyesight and reduce nebula. It is forged from the shells of variegated abalone or wrinkled abalone. Its main functions includeClear liver, improve eyesight, calm nerves, lower blood pressure, suitable for dizziness, blurred vision and high blood pressure caused by excessive liver yang. Secondary functions coverAstringent and hemostasis, regulating immunity, external use can assist in the treatment of ulcers or traumatic bleeding. In terms of content structure, this article will first elaborate on its core functions, and then extend to auxiliary applications and modern research support.

The core function of clearing the liver and improving eyesight

The most significant therapeutic effect of calcined Cassia isClear liver fire, improve eyesight and remove nebula. According to traditional Chinese medicine theory, the liver opens the eyes, and strong liver fire can easily lead to red eyes, dryness or floaters. Calcined Cassia is rich in calcium carbonate and trace elements, which can inhibit excessive liver yang and improve visual fatigue caused by staying up late or overusing the eyes. The ancient book "Compendium of Materia Medica" records that it "mainly treats blue blindness and cataracts, and bone steaming and labor fever". Modern research has also confirmed that its extract has a protective effect on cataract model animals (see Table 1).

The mechanism of calming the liver and subduing yang and lowering blood pressure

Another important effect of burnt cassia isSuppress liver yang and regulate blood pressure. Its calcium ions can antagonize the contraction of vascular smooth muscle and relieve headaches and tinnitus caused by high blood pressure. Clinical observation shows that when used in combination with Uncaria and Gastrodia elata, the systolic blood pressure of patients with essential hypertension can be reduced by an average of 10-15mmHg. Zhang Jingyue, a physician in the Ming Dynasty, emphasized its effect of "suppressing the liver and extinguishing wind" in "Jingyue Complete Book". Modern pharmacology has found that its polysaccharide component can regulate nitric oxide secretion and improve vascular endothelial function.

Auxiliary applications and usage notes

In addition to its core functions, the calcined cassia has a loose texture after being forged, and can be ground into powder and applied externally.Convergence of wounds, can promote healing of minor burns or oral ulcers. It should be noted that it is slightly cold in nature, and those with spleen and stomach deficiency should be combined with Atractylodes macrocephala and Poria cocos to neutralize the medicinal properties. In addition, pregnant women and patients with hypotension should use it with caution. It is recommended to control the dosage under the guidance of a physician (usually 10-15g for oral administration) and avoid long-term use alone.

When using it, treatment should be based on syndrome differentiation, and the medicine should be used in combination with the constitution and symptoms. Current research is mostly focused on the extraction of active ingredients, and its neuroprotective potential may be further explored in the future, giving new value to traditional medicinal materials.
