In the modern world, where health threats such as viral infections, chronic stress, and pollution are ever-present, boosting the immune system has become more important than ever. While pharmaceuticals play a vital role in managing illness, interest in natural and traditional remedies for preventive health care has grown significantly. Herbal medicine, especially from the ancient Indian tradition of Ayurveda, offers a wide array of remedies reputed to support immunity. But how much of this traditional knowledge is backed by science?
In this article, we explore some of the key Indian herbs like and examine what scientific studies say about their role in enhancing immune function.
Understanding immunity and herbal support
The immune system is a complex network of cells, tissues, and organs that defend the body against harmful pathogens. A healthy immune system not only fights infections but also reduces inflammation and maintains balance within the body.
Herbs used in Ayurveda are often classified as Rasayanas, meaning rejuvenators. These herbs are believed to boost vitality, strengthen the body’s resistance to disease, and promote longevity. Modern research is beginning to validate many of these traditional claims. We will discuss some of the prominent herbs that help and have been really good at boosting your immunity capacity.
Tulsi (Ocimum sanctum)
Tulsi, also known as holy basil, the queen of herbs is revered for its spiritual and medicinal value. It is traditionally used to treat respiratory ailments, fevers, and as a general tonic for immunity.
Studies have shown that tulsi possesses significant antioxidant, anti-inflammatory, and immunomodulatory properties. One study published in the Journal of Ethnopharmacology found that tulsi enhances the production of immune cells like T-helper cells and natural killer (NK) cells.

Yashtimadhu (Glycyrrhiza glabra)
In Ayurveda, Yashtimadhu is valued for its sita virya (cooling potency) and its ability to soothe mucous membranes. It’s commonly used in treating coughs, colds, and gastrointestinal inflammation.
Licorice root contains glycyrrhizin, which exhibits strong antiviral activity. Research has shown its effectiveness against viruses like SARS-CoV and influenza. Moreover, it modulates cytokine production, which helps regulate the immune response and reduce inflammation. (Source: Frontiers in Pharmacology)
Ginger (Zingiber officinale)
Both fresh (Ardraka) and dry ginger are widely used in Ayurvedic formulations. Ginger is considered a powerful digestive, anti-inflammatory, and warming herb, often used for colds, nausea, and respiratory issues.
Ginger has been shown to have immunomodulatory effects by enhancing macrophage activity and stimulating the production of antibodies. Its active constituents, like gingerol and shogaol, also reduce inflammation and help in combating respiratory infections.
Pippali (Piper longum)
Pippali is known in Ayurveda for its role in enhancing digestion and metabolism. It’s a key ingredient in Trikatu, a blend of three pungent herbs used to boost bioavailability of other herbs and support respiratory health.
Piperine, the active compound in Pippali, has been studied for its bioenhancing effect, meaning it increases the absorption and effectiveness of other drugs and nutrients (Source: ResearchGate). It also has immunostimulant properties, helping activate immune cells like lymphocytes.
Vasa (Adhatoda vasica)
Traditionally used in respiratory disorders like asthma, bronchitis, and coughs, Vasa is praised for its mucolytic and bronchodilator effects.
Vasicine, the main alkaloid in Vasa, has shown anti-inflammatory and antimicrobial activity. Animal studies indicate that Vasa can modulate immune responses and improve lung function, validating its traditional use in respiratory immunity. (Source: National Library of Medicine)
Devadaru (Cedrus deodara)
Devadaru known as Himalayan Cedar, used in Ayurveda for balancing Vata dosha and treating inflammatory conditions, especially those involving joints and respiratory systems.
Research on Devadaru shows potential anti-inflammatory and antioxidant effects. Some preliminary studies suggest that its extracts may reduce the expression of inflammatory cytokines, thereby supporting immune regulation.
Bilwa (Aegle marmelos)
Bilwa or bael is a versatile herb used to treat digestive disorders, respiratory conditions, and even as a mild tonic for general health.
Bilwa has demonstrated antiviral, antibacterial, and immune-enhancing effects in laboratory studies. Its rich polyphenol content helps reduce oxidative stress, a key factor in immune dysfunction.
Dhundhuka (Anethum sowa)
Often used as a carminative and digestive aid, Dhundhuka is known for reducing bloating and gas. Though less commonly mentioned as an immune herb, its digestive benefits are indirectly supportive of immune health, as gut health is crucial to immunity.
Dill seeds have antimicrobial and antioxidant properties. Their essential oils may reduce inflammation and help maintain a healthy gut microbiome, the key regulators of immune function.
Synergy and Holistic Immune Support
One of the core principles of Ayurveda is synergistic formulation—using combinations of herbs to enhance each other's effects. For example, a blend of tulsi, yashtimadhu, and pippali is often used in Ayurvedic medicine to treat coughs and colds. Such formulations are designed not only to treat symptoms but to strengthen the body’s defense mechanisms from within. BAL Pharma’s Immuwin is one such synergistic formulation that combines multiple herbal ingredients, making an effective medicine for combating colds, cough allergies and boosting the immune system.
Cautions
While herbal remedies offer promising immune support, they are not without caveats. Herbal supplements can interact with medications. For instance, licorice root may interfere with diuretics or corticosteroids. If you have pre-existing health conditions consult a qualified healthcare provider or Ayurvedic practitioner before starting any herbal regimen.
Indian herbs have long been used to support immune function, and modern science is beginning to validate many of these ancient claims. From Tulsi’s adaptogenic power to Ginger’s anti-inflammatory strength, these herbs offer a natural way to bolster the immune system. While more high-quality clinical trials are needed, current evidence suggests that these herbs, when used wisely and appropriately, can play a supportive role in maintaining immune resilience.
Herbal remedies have stood the test of time, offering natural support to our immune systems. By integrating these herbs thoughtfully into our routines, we can harness nature's power to bolster our health and well-being.
