Onion

Often a humble staple in our kitchens, the onion (Allium cepa) holds a significant place in Traditional Chinese Medicine (TCM) for its remarkable health benefits. Far beyond its culinary uses, this pungent bulb is revered for its warming properties and therapeutic potential, addressing a range of common ailments from digestive discomfort to certain infections.

Aliases

In traditional contexts, onion is also known as Jade Onion, Huoti Cong, or Onion Head.

Nature and Flavor

Onion is characterized by a pungent and sweet taste, and a warm nature.

Meridian Tropism

It is traditionally believed to exert its therapeutic effects primarily through the Liver meridian.

Medicinal Part

The medicinal component of the onion plant (Allium cepa) is its bulb.

Onion Dosage and Administration

Internal Use: For internal benefits, onion can be consumed raw or cooked. Typical dosages range from 30 to 120 grams.

External Use: For topical applications, an appropriate amount of onion can be pounded into a paste for compresses or its juice can be applied directly to the affected area.

Onion's Efficacy and Indications

Efficacy: In TCM, onion is valued for its ability to support stomach function and regulate vital energy (Qi), exhibiting detoxifying and antimicrobial properties, and helping to lower blood lipids.

Indications: It is commonly used to address poor appetite accompanied by abdominal distension, aid in the healing of wounds and ulcers, manage conditions like Trichomonas vaginitis, and help with hyperlipidemia (high blood lipid levels).

Onion Combinations

A notable traditional remedy for Trichomonas vaginitis involves combining fresh onion and fresh celery in equal parts. These are pounded into a pulp, and the juice is extracted. An appropriate amount of vinegar is added to this juice. Before sleep, a cotton ball with fleece is dipped into the medicinal juice and inserted into the vagina, to be removed the next morning. This treatment is typically continued for one week, as recorded in the Fujian Materia Medica.

Important Safety Note: While traditional remedies can be insightful, internal or topical application of herbal preparations for sensitive conditions like vaginitis should only be undertaken under the guidance of a qualified healthcare professional. Self-treating can have unintended consequences. Always consult a TCM practitioner or your doctor before using any herbal treatment, especially for infections or chronic conditions.

Onion Contraindications

Individuals experiencing skin itching, eye diseases, or certain stomach ailments are generally advised to avoid or limit their consumption of onion.
