Janu Basti is a localized Ayurvedic oil therapy in which a practitioner molds a ring of black gram dough (urad flour paste) around the knee to create a sealed well, then fills it with warm medicated oil — typically held in place for 30–45 minutes. The warmth and herbal compounds in the oil are absorbed transdermally into the joint and surrounding tissues. It belongs to a broader family of Ayurvedic 'basti' (retention) treatments used across different joints, with 'janu' simply meaning knee in Sanskrit.

The combination of sustained warmth and oil-soluble herbal compounds works together in two ways: the heat relaxes muscle spasm, boosts local circulation, and helps open pores for deeper absorption, while the medicated oil delivers anti-inflammatory plant compounds directly to the knee joint and surrounding cartilage. This bypasses the digestive system entirely, delivering benefits right where they're needed. The gentle hydraulic pressure of the oil pool is also thought to provide a mild decompressive effect on the joint space.

Janu Basti is exclusively a hands-on clinical procedure — it cannot be replicated as a home supplement or capsule. A trained Ayurvedic practitioner or therapist prepares the dough ring, selects the appropriate oil for the person's constitution and condition, heats the oil to a therapeutic temperature, and monitors the session. Some wellness spas offer simplified versions, but the full therapeutic protocol involves preparatory massage (abhyanga) and sometimes follow-up steam treatment.

• Knee osteoarthritis
• Chronic knee pain
• Knee stiffness and reduced mobility
• Rheumatoid arthritis (knee involvement)
• Post-injury knee recovery
• Runner's knee and sports overuse
• Cartilage wear and joint degeneration
• Knee swelling and inflammation

• Progressive functional decline in knee osteoarthritis (regular treatment may help preserve mobility over time)

• Sesame seeds and sesame oil — Sesame is the primary oil base used in most Janu Basti oils — consuming it supports similar anti-inflammatory and joint-lubricating pathways from within.
• Turmeric — Curcumin in turmeric directly targets the same inflammatory pathways that Janu Basti addresses externally — a strong dietary companion for knee inflammation.
• Ginger — Gingerols and shogaols in ginger reduce joint inflammation and pain — regularly used alongside Ayurvedic joint therapies and well-supported for knee osteoarthritis.
• Bone broth and collagen-rich foods — Provides glycosaminoglycans and collagen precursors that support cartilage structure — complements the tissue-nourishing goal of Janu Basti from the inside out.
• Omega-3 rich foods (fatty fish, walnuts, flaxseed) — EPA and DHA reduce systemic joint inflammation, supporting and extending the localized anti-inflammatory effects of medicated oil therapy.

• Mild skin redness or warmth at the treatment site (common, resolves quickly)
• Occasional skin sensitivity or mild rash if allergic to sesame or a specific herbal oil
• Temporary greasiness and oil residue on the skin post-treatment
• Dizziness or lightheadedness if lying in one position too long during session (rare, positional)
• Minor folliculitis or skin irritation if treatment area is not properly cleaned beforehand
• Not suitable during active knee infection, open skin wounds, or acute injury with significant swelling

• Recommended daily: One session of 30–45 minutes per day, typically as part of a 7–14 day treatment course; frequency is determined by practitioner based on severity
• Best time of day: Morning sessions are traditionally preferred in Ayurveda — before the day's activities, when vata (dryness/stiffness) tends to be highest and the body is most receptive to oleation
• With or without food: Ideally performed on a light stomach — not immediately after a heavy meal; some practitioners recommend a light snack 1–2 hours before if sessions are lengthy
• Time to effect: Noticeable stiffness reduction often within 3–5 sessions; meaningful pain relief and mobility improvements typically within 7–14 days of daily treatment
• How long to take it: A standard course is 7 days for mild conditions and 14–21 days for chronic or severe knee conditions; maintenance sessions every 1–3 months are common for ongoing osteoarthritis management
