Chitvan (Saptaparna in Sanskrit), botanically Alstonia scholaris (Apocynaceae), is a large evergreen tree native to the Indian subcontinent, Southeast Asia, and northern Australia. In Ayurveda, it is revered for its febrifuge, anti-malarial, and adaptogenic properties. Modern phytochemical research has isolated potent alkaloids — including echitamine and scholaricine — that validate its traditional uses in fever, respiratory conditions, and nervous exhaustion.

Health Benefits of Chitvan
1. Fever Management and Anti-Malarial Activity
Chitvan bark is one of Ayurveda’s most valued Jwaraghna (fever-relieving) dravyas, particularly for chronic and intermittent fevers. Its bitter alkaloids echitamine and echitamidine have demonstrated anti-plasmodial activity in research studies, supporting its traditional use against malarial fevers. The Sheeta (cooling) virya counteracts Pitta-driven fever, while its bitter taste clears Kapha accumulation that prolongs febrile episodes. Classical texts mention its use in Vishama Jwara (irregular, intermittent fevers).
2. Respiratory Health and Expectorant Action
The bark and leaf decoctions of Chitvan effectively manage Kapha-type respiratory conditions including chronic cough, asthma, and bronchitis. Its Tikta-Kashaya rasa dries excess Kapha in the lungs while its bronchodilatory alkaloids open constricted airways. The powdered bark mixed with honey is a classical preparation for productive cough with thick mucus. Scholars in Ashtanga Hridayam cite Saptaparna bark as a primary herb in Kasahara (anti-tussive) formulations.
3. Digestive Fire Stimulation and Anti-Parasitic Action
Chitvan is a potent Deepana (digestive stimulant) and Krimighna (anti-parasitic) herb used in intestinal worm infestations and sluggish digestion. Its bitter principles stimulate bile secretion and pancreatic enzyme production, improving fat digestion and nutrient absorption. The root bark powder has been used for centuries to expel intestinal helminths. Modern studies confirm antibacterial activity against common gut pathogens including E. coli and Salmonella species.
4. Adaptogenic and Nervine Tonic Properties
Chitvan possesses Medhya (cognitive) and Rasayana (rejuvenating) properties that support mental endurance and recovery from chronic illness. Its alkaloids modulate the HPA axis, reducing cortisol-mediated fatigue and supporting adrenal function — the Ayurvedic analogue of “adaptogenic” action. It is used in debility, nervous exhaustion, and recovery from prolonged fevers where overall vitality is depleted. Combined with Ashwagandha, it serves as a tonic for post-illness convalescence.
5. Skin and Wound Healing
Applied externally, Chitvan bark paste demonstrates Vranaropana (wound-healing) and Kushtaghna (skin-purifying) actions. Its astringent tannins contract wound edges and reduce exudate, while its antimicrobial alkaloids prevent secondary infection. Traditional Ayurvedic practitioners apply a decoction wash for chronic ulcers, infected wounds, and skin conditions aggravated by Pitta-Kapha such as eczema and fungal infections.
6. Liver Protection and Blood Purification
The bitter constituents of Chitvan stimulate hepatic function, supporting detoxification and Raktashodhana (blood purification). Animal studies demonstrate hepatoprotective effects of Alstonia scholaris bark extract against CCl4-induced liver damage. In Ayurvedic practice, it is combined with Kutki (Picrorhiza kurroa) and Bhumyamalaki for chronic liver conditions and skin disorders arising from impure blood.

Side Effects and Precautions
Known Contraindications
- Not recommended in cases of severe Vata imbalance or extreme dryness (Ati Ruksha prakruti) due to its Ruksha (dry) quality.
- Avoid in hypotension — the alkaloids may lower blood pressure further.
- Latex from the tree is caustic; avoid direct skin contact with raw latex.
Drug Interactions
- May potentiate anti-malarial drugs — concurrent use requires medical supervision.
- May interact with anti-hypertensive medications, increasing hypotensive effects.
- Use with caution alongside hepatotoxic drugs due to potential additive liver effects.
Who Should Avoid
- Pregnant women — uterine-stimulating alkaloids may pose risk; avoid without physician consent.
- Breastfeeding women — alkaloid transfer into milk is possible.
- Children under 12 — consult a paediatric Ayurvedic physician before use.
Safe Dosage Range
Bark churna: 1–3 g per day; Decoction: 50–100 ml twice daily. The herb is potent — self-medication at high doses is inadvisable. Always work with a qualified Ayurvedic practitioner for therapeutic use.
Classical Text References
Saptaparna (Chitvan) is listed in Charaka Samhita (Sutra Sthana 4) among the Tikta Skanda (bitter group) herbs used for Jwara (fever), Krimi (parasitic infections), and Kushtha (skin disorders).

What are the main benefits of Chitvan?
Key benefits of Chitvan include its anti-malarial and febrifuge action, expectorant and bronchodilatory effects for respiratory health, anti-parasitic action for gut worms, liver protection, blood purification, and wound-healing properties when applied externally.
Can Chitvan be taken daily?
Chitvan can be taken daily for defined therapeutic periods of 4–8 weeks under medical guidance. Long-term daily use without supervision is not recommended due to its potent alkaloid content. A qualified Ayurvedic physician should assess individual suitability.
What is the correct dosage of Chitvan?
The standard dosage of Chitvan bark powder (churna) is 1–3 g twice daily. The decoction (kwatha) is taken at 50–100 ml twice daily before meals. Standardised extract capsules are typically 250–500 mg twice daily.
Does Chitvan have any side effects?
Chitvan is generally well-tolerated at recommended doses. It may cause dryness and Vata aggravation in susceptible individuals. It may lower blood pressure and should be avoided in hypotension. Pregnant women should not use it without medical guidance due to alkaloid content.
Which dosha does Chitvan balance?
Chitvan primarily balances Kapha and Pitta doshas. Its Sheeta virya (cooling potency) pacifies Pitta-type fevers and inflammation, while its Tikta-Kashaya rasa dries and clears Kapha congestion from the lungs and digestive tract.
