| Basil rich in medicinal properties |
Basil has a rich history in traditional medicine systems around the world and is supported by modern scientific research. Its potential benefits for digestive health, cardiovascular health, and skin health make it a valuable addition to both culinary and medicinal applications.
What is Basil?
Basil, scientifically known as Ocimum basilicum, is a fragrant herb that grows as a small bush, typically reaching heights of 30-60 cm (12-24 inches). It has glossy, oval-shaped leaves that are usually green but can also be purple, depending on the variety. The plant produces small white or pink flowers arranged in clusters.
Basil is native to tropical regions from central Africa to Southeast Asia. It thrives in warm climates and well-drained soil, often found in gardens, farms, and greenhouses. Today, it is widely cultivated worldwide, particularly in Mediterranean countries, India, and Southeast Asia.
Primary Compounds in Basil
The primary bioactive compounds found in basil include:
• Essential Oils: Including eugenol, linalool, cineole, geraniol and methyl chavicol, which contribute to its distinctive aroma and therapeutic properties.
• Flavonoids: Such as vicenin and orientin, known for their antioxidant effects.
• Polyphenols: Including rosmarinic acid, which has anti-inflammatory and antimicrobial properties.
• Vitamins and Minerals: Rich in vitamins A, K, and C, as well as manganese and iron.

Clinical Research on Basil
A 2020 triple-blind study tested 144 patients who had been diagnosed with migraine headaches. The patients were divided into four groups, which included a basil essential oil group, a placebo group and a NSAID group. After three months, the basil essential oil groups had significantly lower pain intensity and frequency of attacks compared to the other groups.
Several studies have found that basil and its essential oils are significantly antibacterial and antifungal.
A 2022 study from the University of Bahrain analyzed research testing basil against different forms of cancer. They analyzed 16 studies that wound that basil leaves have significant anticancer activity. It was also found to slow tumor growth in some of this research.
A 2023 review of research from Indonesia’s University of Padjadjaran investigated the use and effects of basil. They found that it had significant antiviral potential, against both DNA and RNA viruses. It also has significant antibacterial properties against gram-negative and gram-positive bacteria. This is added to their findings of it having significant antifungal effects.
The researchers found that basil’s ability to treat fevers, flu, colds, digestive conditions and lung conditions was well founded.
A 2021 study from the University of Central Chile studied basil’s effects and properties, and found that it had, “several health benefits, such as the prevention of type-2 diabetes, cardio-protection, antioxidant and antimicrobial effects, and anti-inflammatory, antiulcer, anticoagulant, and anti-depressant properties, among others.”
What is the difference between Basil and Holy Basil?
Both basil and holy basil belong to the same plant family and share some things. But they differ significantly in terms of their uses, flavors, and cultural significance.
Both plants are medicinal, and both species are from the Ocimum family. Basil (Ocimum basilicum) is often considered a culinary spice, while Holy basil (Ocimum tenuiflorum) is revered as a medicinal and spiritual therapeutic.
Tulsi is also considered sacred in Hindu culture.
Basil’s leaves are typically more rounded, and Holy Basil has smaller, ovate-shaped leaves with serrated edges. It will often have purple veins with a slightly fuzzy texture. The stems of Tulsi are often hairy and can be purple in color.
Basil renders a sweet, slightly peppery flavor. Holy Basil has a more pungent, spicy flavor. Tulsi is often described as having a stronger aroma and is less commonly used in cooking.
Basil is typically used in Italian dishes, salads, and sauces. It is a staple in recipes like pesto and pizza sauce. Holy Basil will often be used in traditional Indian recipes such as curries. It can also be served as a tea or supplement, to render its health benefits.
