Red sandalwood oil, also known as Pterocarpus santalinus oil, is derived from the heartwood of the endangered red sandalwood tree, endemic to southern India (Andhra Pradesh and Tamil Nadu). Renowned for its deep-hued color, medicinal benefits, and aromatic richness, this oil has a sacred status in Ayurveda, perfumery, and traditional medicine.
From its use in ancient Vedic rituals to high-end skincare formulations worldwide, red sandalwood oil continues to capture global attention. In modern times, scientific studies confirm its antibacterial, anti-inflammatory, antioxidant, and skin-repair properties—reinforcing age-old claims.
1. What Is Red Sandalwood Oil?
1.1 Botanical Origin
Red sandalwood oil is extracted from Pterocarpus santalinus, a slow-growing, hardwood tree that reaches 8–10 meters in height. The tree is protected under CITES Appendix II, meaning international trade is regulated due to conservation concerns. Oil production typically requires 20–30 kg of dried heartwood for just 1 kg of essential oil.

- Used in Ayurvedic formulations for skin rejuvenation and calming effects
- Featured in Vedic rituals and sacred ceremonies
- Valued in Chinese and Tibetan medicine for its antimicrobial and cooling properties
Today, it remains a prized component in luxury perfumes, therapeutic skincare, and wellness blends.
1.3 Chemical Profile
Key constituents include:
- Santalin (sandalwood pigment): Responsible for deep reddish color
- Santalene & Santalenol: Aromatic compounds giving rich, woody fragrance
- Phenolic antioxidants: Provide anti-inflammatory and anti-aging benefits

3. Traditional & Modern Uses
3.1 Traditional Ayurveda
Used for:
- Manjishtadi tailam: Nutritional oil for skin glow
- Treating heat-related conditions (jaundice, fevers)
- Internal tonics in powdered or decoction form for organ support
3.2 Perfumery & Fragrance Industry

4. Extraction Techniques & Quality Standards
4.1 Steam Distillation (Traditional)
- Heartwood is chipped, dried, and ground
- Filled into steam chambers
- Steam separates oil via condensation
- Produces high-quality essential oil but yields are low
4.2 Solvent Extraction (Modern)
- Solvent (hexane or ethanol) is used on powdered heartwood
- Results in absolute—a thicker, more fragrant product
- Offers higher yield but requires solvent removal
4.3 CO₂ Supercritical Extraction (Premium)
- Uses pressurized CO₂ to extract aromatic compounds
- Yields pure, solvent-free oil
- Ensures top pharmaceuticals-grade quality
4.4 Hydrodistillation
- Simpler alternative with water immersion
- Lower-quality, denser oil – often used in dyes or crafts
Extraction Yields:
| Method | Heartwood Required | Oil Yield |
|---|---|---|
| Steam Distillation | ~25 kg | ~1 kg |
| Solvent Extraction | ~20 kg | ~1.3 kg (absolute) |
| CO₂ Extraction | ~20 kg | ~1 kg |
| Hydrodistillation | ~30 kg | ~0.8 kg |
4.5 Quality Testing
Standards include:
- GC/MS analysis for aromatic compounds
- Check sandalin content (>0.1%)
- Verify color, viscosity, refractive index
- Screening for pesticide/solvent residues
4.6 Factors Affecting Oil Quality
- Age of the tree (10–12 years for mature wood)
- Soil minerals & climate specifically red sandy loam in Andhra Pradesh
- Proper drying and storage before extraction
5. Economic & Market Value
5.1 Global Market Demand
- Highly valued in health, beauty, and perfumery sectors
- Annual global demand: several hundred kilograms to over a ton
- Short global supply due to legal protections and slow tree maturity
5.2 Price Range
- Steam-distilled: ₹20,000–₹40,000 per 10 mL bottle
- Absolute/CO₂ grades: ₹35,000–₹60,000 per 10 mL
- Bulk market: ₹2,000,000–₹4,000,000 per kilogram
5.3 Return on Investment (ROI)
A mature acre (~420 trees) can yield 4–5 tons of heartwood. With 3% oil yield:
- 120 kg oil × ₹3 million = ₹36 crore value
- After extraction costs and yields: net returns remain in crores
5.4 India’s Role
- CITES approval (2023) allows plantation-based red sandal exports
- Andhra Pradesh spearheading sustainable production
- Emergence of Jai Prakash Projects and licensed farms promoting regulated supply
5.5 Pricing Trends & Market Drivers
- Surge in natural, toxin-free cosmetics
- Increase in holistic wellness interest
- Religious & premium markets contribute to continued growth
6. Sustainability & Legal Considerations
6.1 Conservation Status
- Listed as endangered by IUCN
- Overharvesting led to habitat loss and illegal trade
- CITES Appendix II regulates trade in plantation-derived products
6.2 Plantation vs. Wild Growth
Legally licit oil must come from artificially propagated plantations. Wild-cut is banned and unenforcible.
6.3 Soil & Plantation Regulation
- Requires soil testing and environmental impact assessments
- Needs tree registration via forest department
- Harvesting/transit requires official permits
6.4 Jai Prakash Projects’ Modern Practices
- We utilize CITES-compliant plantations
- Ensure 24/7 supervision, registered trees, legal harvesting
- Promote ethical and scalable supply chain
7. How To Use Red Sandalwood Oil Safely
7.1 Topical Use
Always dilute (2–5% in carrier oil):
- For acne: use coconut or jojoba oil
- For scarring or pigmentation: evening application around spots
7.2 Aromatherapy

- Combine with lavender or sandalwood (Santalum album) for relax blends
7.3 Internal Use (Only If Food‑grade & GMP-certified)
- Take 1 drop in honey for GI inflammation (consult physician)
- Add trace amounts to topical herbal preparations
7.4 Safety Guidelines
- Sensitive-skin test recommended (patch test)
- Avoid during pregnancy without medical advice
- Store in dark glass bottles, cool place away from sunlight
