Onions are incredibly versatile in the kitchen, whether used in broths, stir-fries, or even raw in salads. According to Vietnam’s Food Composition Table (Nutrition Institute), onions are rich in vitamins and minerals essential for overall health. Notably, they are often hailed as a natural enemy of viruses and bacteria.
Traditional medicine practitioner Bùi Đắc Sáng highlights that placing onions in damp areas, kitchens, or even bedrooms and offices can reduce the risk of viral and bacterial growth. This is because onions act as a natural air purifier, effectively eliminating bacteria, cleansing the air, and boosting immunity.

Mr. Sáng further explains that in traditional medicine, onions are valued for their anti-inflammatory and pain-relieving properties. Modern science confirms that onions contain phytoncides like allicin, a potent antibacterial agent. Allicin effectively targets various infectious bacteria, including E.coli and Salmonella.
Beyond air purification, onions are beneficial for alleviating cold symptoms such as runny nose and congestion. For individuals with sinusitis or seasonal allergies, placing onions in living spaces can help reduce discomfort. For optimal antibacterial effects, it’s best to peel the outer layer and use the inner white core.
Another lesser-known benefit of onions is their ability to enhance physiological function. Modern research reveals that onions contain sulfur compounds and flavonoids, particularly quercetin, which improve blood circulation and vasodilation, thereby enhancing erectile function and reducing libido decline.

Additionally, onions stimulate the production of endogenous testosterone, crucial for maintaining male vitality. A simple way to enhance physiological function is to marinate purple onions in rice vinegar and a bit of honey for 2–3 days. Consume 1–2 tablespoons daily with meals or salads. Alternatively, include onions in daily dishes like stir-fried chicken liver.
However, traditional medicine experts emphasize that using onions to enhance health and vitality should be complemented by early sleep, avoiding alcohol, and regular exercise. Neglecting these habits while relying on onions alone will yield minimal results.
Similarly, while onions are effective and affordable for antibacterial purposes and air purification, comprehensive disease prevention requires a balanced diet, strengthened immunity, and proactive measures. For vaccine-preventable diseases, timely vaccination is essential, and combining it with traditional methods can further enhance prevention efficacy.
