Preparation methods

• Fresh juice (Swarasa): Dilute 15–30 mL in warm water, 1–2 times per day, preferably before meals.
• Powder (Churna): Mix 2–4 g with honey and take twice daily. You can find "Jambira Churna" made from sun-dried lemon peel in some markets.
• Decoction (Kashaya): Boil 5–10 g of peel in 240 mL of water until reduced to half, then filter and sweeten.
• Essential Oil Extraction (for Liniment): Wash and dry citron peels, then chop them. Use a Clevenger apparatus for hydrodistillation. Add the chopped peels to the flask with water (3:1 or 4:1 v/w ratio). Heat gently, allowing steam to carry volatile compounds into the condenser. Collect the condensed liquid, and the essential oil will separate from the water.
• Liniment Preparation: Take soft soap and add water (thrice the quantity of soft soap) and triturate to make a soapy solution. Mix essential oils (e.g., *Citrus medica* oil 4.5-5ml, eucalyptus oil 1ml, mint oil 1ml) and dissolve camphor in it.
• Traditional Practices: Bijapuraka seeds are ground into a paste for snakebite poultices in some tribal areas, though this is under-researched.

Contraindications

• High Pitta conditions: Generally contraindicated in Pittaja disorders and conditions with high Pitta, such as gastritis, burning sensations, and bleeding disorders. Very sour fruits are not suitable in these conditions.
• Consumption with milk: Should not be consumed along with milk.
• Peptic ulcer disease: High citric acid content may aggravate ulcers in susceptible individuals.
• Kidney stone history: Use with caution if prone to oxalate stones due to the presence of citrus oxalates.

Side effects

• Possible enamel erosion, reflux, or skin sensitivity if misused. Dilutions and rinsing can help prevent issues.
• Highly contraindicated in Pittaja disorders and high Pitta conditions like gastritis, burning sensations, and bleeding disorders.
• Unripe fruits can be unhealthy.
• Very sour fruits are contraindicated in high Pitta conditions such as bleeding disorders, nasal bleeding, burning sensation, and gastritis.

Interactions

• Bijapuraka should not be consumed along with milk.
• The petroleum ether extract of *Citrus medica* seeds may have anti-diabetic, hypocholesterolemic, and hypolipidemic effects and may interact with related medications.
• Few long-term safety trials exist for high-dose citrus peel extracts.

Clinical evidence

Studies suggest Citrus medica extracts possess antimicrobial, antiulcer, and anticancer properties. Research indicates antioxidant activity due to ascorbic acid, phenolics, flavonoids, and carotenoids. Preliminary evidence suggests potential sedative and hypnotic effects. More comprehensive clinical trials are needed to validate these traditional uses.
