Traditional applications and pharmacological effects

The herb is listed as a middle grade in the "Shen Nong's Materia Medica". Traditional Chinese medicine believes that it is slightly cold in nature and belongs to the bladder meridian.

Modern research and clinical validation

In recent years, studies have found that the ethanol extract of Cortex acuminata has an inhibitory rate of more than 75% against Staphylococcus aureus (see table below), and its anti-inflammatory effect is related to the inhibition of the NF-κB pathway. In clinical practice, it is often used in combination with Qumai, talc, etc. to treat acute cystitis, with an effective rate of up to 82%. In addition, external washing of its decoction can relieve the itching of eczema, but long-term use should be avoided to prevent dry skin.

Precautions and contraindications for use

Although Cortex Cortex is a natural medicinal material, it should be used with caution by those with spleen and stomach deficiency, as it may cause diarrhea; pregnant women should use it under the guidance of a physician. The normal dosage is 9-15 grams (dry product). Excessive dosage may cause nausea. When using it externally, you need to test your skin sensitivity and avoid taking it with spicy food. It is worth noting that its insecticidal effect only has an auxiliary effect on roundworms and hookworms and cannot replace anthelmintic drugs.

When using it, it is necessary to differentiate and treat it, adjust the dosage according to your physical constitution, and pay attention to the incompatibility (for example, it should not be used with warm tonic medicine). It is recommended to use it as an auxiliary treatment under the guidance of a doctor, rather than as a single therapy, to maximize safety and effectiveness.
