What is Peelu?
Peelu, known in Sanskrit as Pilu (पिलु), is a significant medicinal plant in Ayurveda with the botanical name Salvadora persica. It is a shrub or small tree native to the arid and semi-arid regions of India, Africa, and the Middle East, prized for centuries as the source of the traditional tooth-cleaning stick known as Miswak or Datun. Peelu’s twigs, roots, bark, and seeds each carry distinct therapeutic applications.

Health Benefits of Peelu
- Oral Health and Dental Hygiene
Peelu twigs are the basis of the ancient Miswak toothbrush, endorsed by both Ayurveda and Islamic tradition for maintaining oral health. The natural silica in Peelu effectively removes plaque and surface stains, while tannins provide astringent action that strengthens gums and reduces gingivitis. Antibacterial compounds in the twig inhibit Streptococcus mutans and other cavity-causing bacteria. - Halitosis (Bad Breath) Elimination
Peelu contains natural aromatic compounds including benzyl isothiocyanate that neutralise odour-causing bacteria in the mouth. Regular use of Peelu twigs or Peelu-based mouthwash provides fresh breath naturally without synthetic chemicals. This makes it one of the most effective and time-tested herbal remedies for chronic bad breath. - Digestive Health and Mild Laxative Action
In Ayurveda, Peelu seeds and bark are used to improve digestive fire (Agni) and relieve constipation through their mild laxative properties. The bitter and pungent taste stimulates bile secretion and intestinal motility, helping to clear accumulated toxins (ama) from the gut. It is particularly indicated in Kapha-type digestive sluggishness. - Anti-inflammatory and Antimicrobial Action
Peelu possesses broad-spectrum antimicrobial activity against both gram-positive and gram-negative bacteria, making it useful in managing infections of the skin, throat, and urinary tract. Its anti-inflammatory properties help reduce swelling and redness in tissues, supporting faster recovery from minor infections and inflammations. - Antioxidant Protection
Rich in flavonoids, alkaloids, and isothiocyanates, Peelu demonstrates significant antioxidant capacity. These compounds help protect cells from oxidative damage, potentially reducing risk of chronic diseases and supporting healthy ageing. Regular consumption of Peelu preparations contributes to overall cellular health and longevity.
How to Use Peelu
| Form | Dosage | How to Take |
|---|---|---|
| Miswak twig (oral hygiene) | 1 fresh twig daily | Chew end to expose fibres; brush teeth and gums for 2–3 minutes |
| Bark decoction | 20–30 ml twice daily | Boil 5 g bark in 200 ml water; reduce and drink warm for digestive benefits |
| Seed powder | 1–2 g once daily | Mix with warm water or honey; take after meals for laxative effect |
Side Effects & Precautions
Peelu is generally safe when used appropriately. People with allergies to the Salvadoraceae plant family may experience skin rashes, itching, or swelling. Overuse of Peelu twigs may irritate the oral mucosa. Individuals with irritable bowel syndrome (IBS) or inflammatory bowel conditions should consult a healthcare provider before using Peelu for its laxative effects. Those with existing gum lesions should use it gently to avoid aggravation.

Ashtanga Hridayam includes Peelu in several topical and digestive preparations, highlighting its versatility as a medicinal plant.
