Tulsi Herb

The predominant cause of global morbidity and mortality is lifestyle-related chronic diseases, many of which can be addressed through Ayurveda with its focus on healthy lifestyle practices and regular consumption of adaptogenic herbs. Of all the herbs used within Ayurveda, tulsi (Ocimum sanctum Linn) is preeminent, and scientific research is now confirming its beneficial effects. There is mounting evidence that tulsi can address physical, chemical, metabolic and psychological stress through a unique combination of pharmacological actions. Tulsi has been found to protect organs and tissues against chemical stress from industrial pollutants and heavy metals, and physical stress from prolonged physical exertion, ischemia, physical restraint and exposure to cold and excessive noise. Tulsi has also been shown to counter metabolic stress through normalization of blood glucose, blood pressure and lipid levels, and psychological stress through positive effects on memory and cognitive function and through its anxiolytic and anti-depressant properties. Tulsi’s broad-spectrum antimicrobial activity, which includes activity against a range of human and animal pathogens, suggests it can be used as a hand sanitizer, mouthwash and water purifier as well as in animal rearing, wound healing, the preservation of food stuffs and herbal raw materials and traveler’s health. Cultivation of tulsi plants has both spiritual and practical significance that connects the grower to the creative powers of nature, and organic cultivation offers solutions for food security, rural poverty, hunger, environmental degradation and climate change. The use of tulsi in daily rituals is a testament to Ayurvedic wisdom and provides an example of ancient knowledge offering solutions to modern problems.

What Is Tulsi Tea? Benefits, Uses, & Recipes

Tulsi, an Ayurvedic herb widely used in therapeutic herbal tea/tisane and true tea blends, may be called Tulasi, holy basil, “The Incomparable One,” “Elixir of Life,” or “Queen of the Herbs.” Native to India and cultivated throughout Southeast Asia, it’s considered a foundational herb that, combined with other adaptogenic herbs, can help the body withstand many forms of stress.

It’s been harvested for use in Ayurvedic treatments for 5,000 years and has a strong aroma and a flavor that can range from peppery to astringent.

6 Health Benefits of Tulsi Tea:

Tulsi has been used for centuries to cure symptoms of various diseases and ailments, but its power as an adaptogen gets the most notice in modern times. Some scientific studies have shown its efficacy as an anti-inflammatory, anxiety treatment, and antioxidant, although no large-scale formal research has been undertaken in the United States.

Combats Respiratory Ailments

Tulsi may relieve symptoms of asthma, bronchitis, colds, congestion, coughs, flu, sinusitis, sore throat, and similar ailments. To clear your sinuses, inhale the steam from a fresh cup of tea before you drink it.

Lowers Blood Pressure and Reduces Stress

Regular consumption of tulsi may lower blood pressure and cholesterol by regulating cortisol levels, reducing the risk of stroke, heart attack, and other related diseases. It can also help relieve headaches and may lessen anxiety and depression for some. Regular consumption may lead to better sleep.

Treats Gastrointestinal Disorders

Tulsi can be used to treat indigestion, intestinal parasites, ulcers, vomiting, gastric disorders, and stomach or menstrual cramps. It may also reduce pain from kidney stones and could help prevent them.

Relieves Arthritis

Tulsi tea may help reduce inflammation and relieve the joint pain associated with arthritis.

Regulates Blood Sugar

Drinking tulsi tea can help maintain stable blood sugar levels. It may also improve metabolism and promote the efficient processing of carbohydrates and fats.


Tulsi may kill damaging bacteria in the mouth, resulting in cleaner teeth and fresher breath. It can also alleviate acne, slow the effects of aging, and relieve the itch or sting of bug bites.


Alternative medicine practitioners use tulsi as a powerful adaptogenic herb (an herb that reduces stress and increases energy). It may also reduce the frequency and severity of asthma attacks, work as an anti-inflammatory, and promote detoxification. It can modulate the immune system and protect the liver from environmental toxins. In the United States, tulsi is most commonly found packaged for use as an herbal. In Asia, cooks often add fresh holy basil leaves to stir-fries or soups.

How to Drink Tulsi Tea

One easy way to consume tulsi is to brew an herbal tea or an herbal infusion. To make tulsi tea, boil 1 cup of filtered water and pour it over 1 teaspoon of fresh tulsi leaves, 1/2 teaspoon of dried tulsi leaves, or 1/3 teaspoon of tulsi powder. Cover the water in a pot or mug and let it steep for 20 minutes (or longer, if you want to maximize the health benefits). Then strain the leaves, add honey if desired, and enjoy.

Caffeine Content in Tulsi Tea

Tulsi tea is caffeine free and can be safely consumed up to six times a day. However, tea producers often combine tulsi with black, green, or white tea leaves, so check the package carefully if you want to avoid caffeine.

Buying and Storing

You can buy loose dry tulsi at natural food stores, from specialty tea retailers, or online. It’s also available as the main ingredient in a selection of packaged herbal teas or as a powdered drink mix. Store dried tulsi in an airtight container in a cool, dark, dry location such as your pantry or a cupboard and use it within a year of purchase for the greatest health benefits. It’s also an easy plant to grow in pots at home; most Indian households have multiple tulsi plants.

Types of Tulsi Tea

  • Rama Tulsi (also known as green leaf tulsi): A green tulsi with light purple flowers and an aromatic, clove like scent (thanks to its chemical component of eugenic, which is the main aroma in cloves) and mellower flavor.
  • Krishna Tulsi (also known as Shyama Tulsi or purple leaf tulsi): A purple plant with a clove-like aroma and peppery flavor.
  • Vana Tulsi (or wild leaf tulsi): A bright, light green tulsi plant that grows wild and is indigenous to many areas of Asia; it has a more lemony aroma and flavor.

Of the three types of tulsi, Krishna tulsi is often considered to be the most beneficial to health, followed closely by Rama tulsi. Vana tulsi has less potency, but it is sometimes blended with other types of tulsi for a more pleasing flavor.

Side Effects

Tulsi may decrease fertility in men and women, so anyone hoping to conceive should refrain from consuming large quantities of tulsi. It’s also recommended that women avoid tulsi while breastfeeding. Some people experience nausea or diarrhea when they first add tulsi tea to their diet, so it’s best to start with small quantities and increase your consumption over time. Tulsi may also slow blood clotting, so doctors generally tell patients to avoid it for at least two weeks before and after any surgery.

Tulsi may interfere with pharmaceutical drugs, so it’s best to confer with your doctor if you’re being treated with medications for any chronic or acute condition before you start using it.

The Health Benefits of Holy Basil

Not your basic basil

Holy basil (Ocimum tenuiflorum) isn’t like the sweet basil in your mom’s marinara sauce or the Thai herb you use to flavor a steaming bowl of pho. This green leafy plant, also known as Ocimum sanctum L. and tulsi, is native to Southeast Asia. It has a history within Indian medicine as a treatment for many conditions, from eye diseases to ringworms.

From the leaves to the seed, holy basil is considered a tonic for the body, mind, and spirit. Different parts of the plant are recommended for treating different conditions:

According to the Journal of Ayurveda and Integrative Medicine, holy basil has antidepressant and anti-anxiety properties comparable to diazepam and antidepressant drugs. These studies examined the leaves. One study found that people who took 500 milligrams (mg) of holy basil extract each day felt less anxious, stressed, and depressed. People also felt more social.

Ayurvedic practitioners recommend drinking holy basil as tea using the leaves. And since it’s caffeine-free, it’s okay and even recommended to drink daily. The act of drinking tea can be ritualistic and as calming as yoga. It fosters clear thoughts, relaxation, and a sense of well-being.

But if the basil’s bitter and spicy flavor isn’t your cup of tea, a supplement in pill form or as an alcohol extract is available. There is less risk of contamination when taking an herb in natural form.

The researchers note, however, that more studies are needed to clarify the beneficial dosage for different populations.

Respiratory Infections

In a 2009 study on mice, scientists discovered that dietary supplementation with tulsi and clove protected the animals’ lungs against colonization with Klebsiella pneumonia, a common hospital-acquired bacteria known to cause pneumonia and urinary tract infections.

Mercury Poisoning

A 2002 study on mice suggests that treatment with tulsi may provide protection against mercury-induced toxicity, which known to damage the central nervous system, endocrine system, kidneys, and other organs.

Possible Side Effects

Like other supplements, little is known about the safety of long-term or regular use of tulsi due to a lack of research.

Tulsi may lower blood sugar and should be used with caution in people who have diabetes and are on blood-sugar-lowering medication.

Women who are pregnant or trying to get pregnant should not take tulsi as it may affect reproductive capacity, possibly due to its ursolic acid content. Tulsi may increase testosterone levels.

While small amounts of tulsi may prevent toxin-induced damage to the liver, in greater amounts eugenol may cause liver damage. Overdose is also possible, causing symptoms such as nausea, diarrhea, rapid heartbeat, or convulsions.
