What are the characteristics of the Oxalis plant?
Oxalis, commonly known as wood sorrel, is a plant that belongs to the Oxalidaceae family. It can be further categorized into two types: red-flowered oxalis and yellow-flowered oxalis.
Yellow-flowered Oxalis: This variety is a perennial plant with a creeping herbaceous stem that grows close to the ground. The stem is usually hairy and light red in color. The leaves are long-stalked, alternately arranged, very thin, and heart-shaped. The flowers are yellow, and the fruits are elongated.
Red-flowered Oxalis: This type of oxalis can grow up to a height of 20 to 30 cm. It has long-stalked leaves that are compound, hairy, and slightly black on the underside.
In Vietnam, oxalis can be found in many provinces and cities across the country, from the North to the South. It prefers moist environments and can tolerate shade. It often grows wild on paddy fields, fallow land, or even in home gardens.
Unlike most herbs, which are typically used in their dried form, oxalis is predominantly used in its fresh form. While some remedies utilize all parts of the plant, others specifically use only the fresh leaves. The ideal time to harvest oxalis is from June to July.
Health Benefits of Oxalis
Oxalis offers a range of health benefits. Additionally, combining oxalis with other medicinal herbs can result in highly effective treatments. Here are some popular remedies:
– Sore Throat Treatment: Sore throat can be extremely uncomfortable, and if left untreated, it may lead to more serious health concerns. One of the natural remedies for sore throat involves the use of fresh yellow-flowered oxalis. Simply chew the oxalis leaves with a pinch of salt and slowly swallow the mixture.
– Fever Reduction: Oxalis is known for its cooling properties. To treat high fever, wash and crush the yellow-flowered oxalis, add water, and then squeeze the mixture to extract the juice. Give this juice to the patient to help reduce their body temperature.
– Cough Remedy: Oxalis can be beneficial if you’re suffering from a cough. To prepare this remedy, you’ll need yellow-flowered oxalis along with other fresh ingredients like Centella asiatica (gotu kola), ribwort plantain, or chickweed. Crush the fresh herbs into a paste, add a teaspoon of sugar, and boil the mixture. Drink this concoction throughout the day, dividing it into three doses.
For whooping cough, a more intensive remedy can be prepared using oxalis leaves, ribwort plantain leaves, lemon root, and other herbs like chives, bitter melon seeds, and alum. Boil these ingredients with a little sugar, and then drink the concentrated liquid.

+ Use oxalis to prepare a decoction and drink it throughout the day.
