In Vietnam, lemon basil leaves are sold for approximately 50,000 to 70,000 VND per kilogram. However, only a few people use the fresh leaves as herbs, cook them in porridge or beef stir-fries, sour soups, or as a remedy for coughs and colds. Many people are unaware of the benefits of lemon basil and tend to discard or avoid consuming it.

According to Doctor Vu, in traditional Chinese medicine, lemon basil has a sour and pungent taste, a warm nature, and enters the lung meridian. It is used to relieve colds, dissolve phlegm, detoxify, and treat symptoms of colds, lung coldness, wind-cold, phlegm-heat, and bacterial infections. It is also effective in treating sore throats, inducing sweating, and relieving coughs and colds. With these benefits, lemon basil can be consumed fresh or brewed into a drink to relieve colds and warm the stomach.

In the Southern traditional medicine industry, lemon basil is often steam-distilled to extract its essential oil, which is then combined with other herbs to produce cough and cold remedies.

Modern medicine has found that lemon basil contains phenolic compounds, salicylates, carvacrol, eugenol, and caryophyllene. Notably, it is rich in vitamins A and C and Omega 6, offering potential health benefits such as:

Skin and eye health

Research indicates that vitamin A in lemon basil is beneficial for vision and is an essential component of the immune system. It helps prevent oxidation and improves inflammatory skin conditions such as acne and psoriasis.

The juice extracted from lemon basil leaves has a diuretic effect, helping the body eliminate toxins by increasing urination. This process also reduces excess salt, water, and fat in the body, improving kidney function.

Blood sugar control
