This page analize the most important medicinal aspects of Allium cepa.
Health Benefits
Allium cepa fights cancer cells by containing bioactive compounds such as sulfur-containing compounds and flavonoids, which have been shown to inhibit the growth of cancer cells and induce apoptosis, or programmed cell death, in malignant tissues.
These compounds also help reduce oxidative stress by neutralizing free radicals, which are known to damage cellular structures and contribute to the development of chronic diseases. By reducing oxidative stress, Allium cepa supports overall cellular health and may slow the progression of diseases linked to oxidative damage. Additionally, the herb boosts the immune system by enhancing the activity of immune cells such as macrophages and lymphocytes, which are crucial for detecting and eliminating harmful pathogens.
Regular consumption of Allium cepa may therefore reduce cancer risk by combining its anti-carcinogenic properties with its immune-boosting effects, making it a valuable natural remedy in promoting long-term health and disease prevention.

Bioactive Constituents
Allium cepa sulfenic acid is a key compound found in garlic, known for its potent antimicrobial properties.
This sulfur-containing compound is primarily formed when garlic is crushed or chopped, triggering a chemical reaction that converts alliin into allicin, another important medicinal constituent. Sulfenic acid also contributes to the characteristic pungent odor of garlic and plays a role in its ability to enhance immune function.
Alongside sulfenic acid, quercetin, a flavonoid antioxidant, is present in garlic and helps reduce inflammation and oxidative stress in the body. Together, these compounds—sulfenic acid, alliin, allicin, and quercetin—work synergistically to provide garlic with its wide range of health benefits, including cardiovascular support, anti-inflammatory effects, and potential anticancer properties.
These natural constituents have been studied extensively for their therapeutic applications and are widely recognized in both traditional and modern medicine.
The 7 best bioactive constituents of Allium cepa are shown in the image below.
The list below give a brief description of the 13 best bioactive constituents of Allium cepa.
- Sulfenic Acid: A sulfur-containing compound that contributes to the pungent smell of onions and may have antimicrobial properties.
- Alliin: An amino acid derivative that is converted into allicin when the onion is cut or crushed, contributing to its medicinal properties.
- Allicin: A sulfur compound known for its antimicrobial, anti-inflammatory, and immune-boosting properties.
- Quercetin: A flavonoid with antioxidant, anti-inflammatory, and antiviral properties that supports overall health.
- Flavonols: A class of plant compounds with antioxidant and anti-inflammatory effects that may support cardiovascular and immune health.
- Glucosinolates: Compounds that may help in detoxification and have potential anti-cancer properties when metabolized in the body.
- Saponins: Natural compounds that may support immune function, have anti-inflammatory properties, and aid in digestion.
Medicinal Parts
Allium cepa seed, commonly known as the seed of the onion, is rarely used in traditional medicine due to its limited availability and the plant's primary medicinal use being derived from its bulb rather than its seed.
While the seed itself is not a major component in medicinal formulations, it contains compounds such as sulfur-containing volatile oils that may contribute to its potential therapeutic properties. These compounds are believed to have antimicrobial and anti-inflammatory effects, though research on their specific applications is limited. In some traditional practices, the seed may be used in combination with other parts of the plant to enhance its medicinal profile.
Overall, the seed's role in medicinal applications is secondary compared to the bulb, and further scientific investigation is needed to fully understand its potential benefits.

Herbal Preparations
Allium cepa tinctures are commonly used in homeopathic medicine to treat symptoms such as runny nose, watery eyes, and sinus congestion, often associated with colds or allergies.
These tinctures are prepared by soaking the dried Allium cepa bulbs in alcohol, allowing the active compounds to dissolve and create a concentrated remedy. The tinctures are typically taken orally in small doses, often diluted in water or under the tongue for rapid absorption. They are particularly effective for individuals experiencing a burning sensation in the nose and eyes, along with a tendency to sneeze.
In addition to tinctures, Allium cepa can be prepared as teas, capsules, or decoctions, each offering different methods of consumption and absorption. Teas, for instance, are made by steeping the dried herb in hot water, while capsules provide a more convenient and standardized dosage. These various preparations allow for flexible use in addressing respiratory and inflammatory conditions.
Whether used as a gargle, cream, or lozenge, Allium cepa remains a versatile herbal remedy with a wide range of applications in traditional and alternative medicine.
