Solar Eclipse 2026: Why are basil leaves added to food items during solar eclipse? Know the science behind this age-old tradition and its 7 miraculous health benefits.


The astronomical and religious event of Solar Eclipse 2026 has always been the center of special curiosity and faith in the country and around the world. In Sanatan tradition, the eclipse and its Sutak period are considered to be a very sensitive time. Whenever the time of a solar eclipse or lunar eclipse approaches, a familiar tradition that has been going on for centuries in Indian homes is immediately activated—the elderly women and elders of the house put green basil leaves (Tulsi Leaves / Holy Basil) in pots of drinking water, milk, curd, cooked food and dry grains. There is a religious belief that by adding Tulsi Dal, the food does not become impure due to the ill effects of the eclipse and remains edible even after the eclipse ends. But have you ever thought that this ritual started by our ancestors is only a religious belief, or there is some deep biological, chemical and scientific basis hidden behind it? Let us understand from the perspective of modern science, biochemistry and Ayurveda, what is the real secret of adding basil in eclipse and how this green leaf works as nectar for our body.

Religious and mythological belief of adding basil in food and drinks during eclipse

In Sanatan scriptures and Puranas, Tulsi is not just a plant but has been given the status of ‘Vishnupriya’ and a great medicine. According to Padma Purana and Skanda Purana, Tulsi is considered to be the abode of all the pilgrims and deities. The eclipse period is considered to be the time of influence of Rahu-Ketu and transmission of negative energy.

According to the scriptures, during the eclipse, subtle negative waves and impurities increase in the atmosphere, which can contaminate food and water. Tulsi is considered the most sacred and virtuous plant. It is believed that the food which is touched by a Tulsi leaf is not affected by the defects of Rahu or the negative effects of eclipse and it remains pure as Prasad. Tulsi leaves are plucked and kept before the beginning of the Sutak period, because touching the Tulsi plant or plucking its leaves during the eclipse period is considered taboo.

What does science say? The truth about food safety from radiation and bacteria

When we review this tradition on the basis of modern science and the laws of physics, the extraordinary scientific vision of our ancient sages comes to the fore.

During an eclipse, when the Moon comes between the Sun and the Earth, the balance of natural ultraviolet rays and light waves coming from the Sun suddenly changes. Natural sunlight works to destroy bacteria and harmful microorganisms present in the environment. When this natural light is blocked during the eclipse, harmful pathogens and bacteria present in the air become increasingly active. Along with this, many types of cosmic rays spread in the atmosphere.

Basil leaves have amazing biochemical and anti-radiation properties:

  • Anti-Bacterial and Anti-Microbial Armor: Powerful volatile oils like ‘Eugenol’, ‘Carvacrol’ and ‘Caryophyllene’ are found in basil leaves. These elements are natural disinfectants and do not allow any type of bacteria to grow in the food.

  • Amazing ability to absorb radiation: Many scientific researches have proved that the Tulsi plant and its leaves have extraordinary ability to absorb electromagnetic radiation and harmful rays. When basil leaves are added to food or water, it prevents the chemical balance of the liquids from getting disturbed and slows down the process of oxidation (Fermentation/Spoilage) in the food.

  • Natural Preservation of Food: Due to the moisture in milk and cooked food, they spoil fastest during the eclipse. The anti-oxidants present in basil keep the pH level of the food stable, which prevents the food from becoming stale or poisonous.

Not just eclipse, you get these 7 miraculous health benefits by consuming Tulsi daily.

In Ayurveda, Tulsi has been called the ‘Queen of Herbs’. This simple looking green leaf is no less than a boon for the overall health of our body. By consuming it in daily life, the body gets these major benefits:

  • 1. Makes immunity strong: Basil contains abundant amounts of vitamin C, zinc and powerful antioxidants. It activates the T-helper cells and natural killer cells of our body, thereby protecting the body from seasonal flu, viral infections and diseases caused by changing weather.

  • 2. Panacea for lungs and respiratory system: Basil leaves have expectorant properties. It melts the mucus accumulated in the chest and expels it. Basil tea or decoction is extremely beneficial for patients suffering from asthma, bronchitis, chronic cough and sore throat.

  • 3. Natural Stress Buster and Depression Relief: Tulsi is a powerful ‘Adaptogen’. It controls the level of stress causing hormone ‘Cortisol’ in the body. Drinking extract of basil leaves every morning provides relief from mental stress, nervousness and anxiety and keeps the mind calm.

  • 4. Controls blood sugar and diabetes: According to clinical studies, basil leaves improve the function of beta cells of the pancreas and increase insulin sensitivity. With regular consumption, fasting blood sugar (fasting glucose) and post-meal sugar levels remain balanced.

  • 5. Heart health and elimination of bad cholesterol: The eugenol present in basil helps in maintaining normal blood pressure and prevents the accumulation of LDL (bad cholesterol) and triglycerides in the arteries, thereby reducing the risk of heart attack and stroke.

  • 6. Improves digestion and relieves gas and constipation: Tulsi stimulates the secretion of digestive juices and enzymes. It neutralizes the excessive acid produced in the stomach, thereby eliminating the problems of acidity, flatulence, sour belching and indigestion.

  • 7. Natural detox of body and glowing skin: Tulsi purifies the blood naturally. It removes toxic elements from the body and removes skin problems like acne, blemishes and eczema, which gives a natural glow to the face.

Why should one never eat basil leaves by chewing them? Know the opinion of dental experts

Often people wake up in the morning and eat basil leaves by chewing them directly with their teeth, but according to dentists and Ayurveda experts, doing so can prove to be extremely harmful for the teeth.

Trace elements of mercury and iron are naturally found in basil leaves. Along with this, it contains some acidic components. When we chew basil leaves repeatedly with our teeth, this mercury and acid directly come in contact with the outer protective shield of the teeth i.e. ‘tooth enamel’. Due to this, the tooth enamel starts wearing away, yellowness of teeth, sensitivity and the risk of infection increases. Therefore, basil leaves should never be chewed, but should be swallowed directly with water or used in the form of decoction and tea.

According to Ayurveda, the right way and time to consume Tulsi

To get the full medicinal benefits of Tulsi, it is necessary to consume it in the right way:

  • Consume on empty stomach in the morning: In the morning, after brushing your teeth, swallow 4 to 5 fresh basil leaves directly with a glass of lukewarm water.

  • Herbal decoction of basil-ginger: Add 5-6 basil leaves, a little ginger, a pinch of black pepper and cinnamon in water and boil for 5 minutes. Filter it and add some honey and drink it. This decoction instantly boosts the energy and immunity of the body.

  • Tulsi Water: Fill a copper or glass jug with water at night and put 8-10 basil leaves in it. Drink this water throughout the day, it detoxifies the body from inside.

The traditions of Sanatan Dharma are not mere blind imitation, but contain deep scientific and natural knowledge behind them. The custom of adding Tulsi to food during a solar eclipse is a symbol of the same advanced science of our ancestors, which is completely relevant even today to protect human health and the environment.
