Health Benefits of Mulethi
- Respiratory Relief and Cough Management
Mulethi is revered in Ayurveda as a premier herb for the lungs and throat. Its soothing, expectorant qualities help loosen mucus, reduce airway inflammation, and ease breathing in conditions such as bronchitis, asthma, and chronic dry cough. Regular use of Mulethi decoction or powder supports the restoration of healthy respiratory function. - Digestive Support and Ulcer Healing
The demulcent and anti-inflammatory properties of Mulethi make it highly effective for healing peptic ulcers, managing acid reflux, and soothing gastritis. It forms a protective coating on the gastric mucosa, reducing irritation and promoting tissue repair. Ayurvedic physicians frequently recommend Mulethi for hyperacidity and inflammatory bowel conditions. - Liver Protection and Detoxification
Mulethi supports liver function by stimulating the production of bile and promoting the elimination of toxins. Glycyrrhizin, its primary active compound, exhibits hepatoprotective effects that help regenerate liver cells and combat oxidative stress. It is used in classical Ayurveda for jaundice and liver congestion. - Skin Health and Anti-ageing
Applied topically or consumed internally, Mulethi brightens skin tone, reduces hyperpigmentation, and soothes inflammatory skin conditions like eczema and dermatitis. Its antioxidant content combats free radical damage, helping to maintain a youthful complexion. It is a common ingredient in traditional Ayurvedic beauty formulations. - Immunity Enhancement and Adaptogenic Action
As a natural adaptogen, Mulethi helps the body cope with physical and emotional stress by modulating the adrenal glands. It strengthens immunity through its antiviral and antimicrobial properties, making it useful during seasonal infections, fever, and general debility. Regular consumption supports overall vitality and resilience. - Hormonal Balance and Women’s Health
Mulethi contains phytoestrogens that gently modulate hormonal activity, making it beneficial for managing menstrual irregularities, menopausal symptoms, and polycystic ovarian syndrome (PCOS). Its calming effect on Vata and Pitta helps reduce menstrual cramps and mood swings associated with hormonal fluctuations.

Side Effects & Precautions
Mulethi is generally safe when used within recommended doses. However, long-term or excessive use can elevate blood pressure, cause fluid retention, and reduce potassium levels due to glycyrrhizin content. People with hypertension, heart disease, kidney disorders, or those on corticosteroid therapy should avoid it or use only under medical supervision. Pregnant women should not consume large doses. Deglycyrrhizinated licorice (DGL) preparations are available as safer alternatives for those with these concerns.
Classical References
Mulethi is extensively described in the foundational Ayurvedic texts. Charaka Samhita (Sutrasthana 4) lists Yashtimadhu among the best herbs for voice, throat, and complexion (Varnya, Kantya mahakashayas). Sushruta Samhita includes it in the Madhura varga and recommends it for wound healing, eye disorders, and rasayana therapy. Ashtanga Hridayam by Vagbhata references it in multiple formulations including Yashtimadhu ghrita for brain nourishment and Saraswatarishta for cognitive health.
