Saha (Vajradanti, Porcupine flower)

About

Saha, botanically known as Barleria prionitis, is an Ayurvedic herb traditionally used for its anti-inflammatory, antimicrobial, and wound-healing properties. It is employed in managing skin diseases, fever, cough, and inflammatory conditions. Modern research supports its use in dermatology and as an anti-diabetic agent.

Properties

COX-2 inhibition, Antimicrobial activity

Dosage

Powder (Churna): 1–2 g, twice daily, mixed with warm water or honey, best for digestive and Pitta-related issues. Decoction (Kwath): 10–15 g of dried root/leaf boiled in 200 ml of water, reduced to 50 ml. Sip half before meals to reduce inflammation systemically. Topical Paste: Fresh leaf powder (10 g) mixed with honey and a few drops of sesame oil. Apply to boils, wounds, or acne lesions daily for 7–10 days. Extracts (Tincture): 1:5 hydroalcoholic extract, 5–10 ml in water, often used as an adjunct in liver-support blends. For antidiabetic activity, a study used 200 mg/kg body weight of alcoholic extract of leaves and roots in rats for 2 weeks. Flower extract for analgesic activity was used at a dose of 50 mg/kg body weight in mice.
