What is Amaltas?
Amaltas, known in Sanskrit as Aragvadha (आरग्वध) or Suvarna, is a celebrated medicinal tree in Ayurveda with the botanical name Cassia fistula, belonging to the Fabaceae family. Commonly called the Golden Shower Tree or Purging Cassia in English, this ornamental and medicinal tree is native to the Indian subcontinent and Southeast Asia. The Sanskrit name Aragvadha means “disease killer,” a testament to its wide-ranging medicinal applications documented across classical Ayurvedic texts.

Health Benefits of Amaltas
- Gentle Laxative and Constipation Relief
Amaltas fruit pulp is one of Ayurveda’s most favoured mild laxatives (mridu virechana), effective for relieving chronic constipation in people of all ages including children and the elderly. Unlike harsh purgatives, the fruit pulp of Amaltas works gently, softening stools and promoting smooth bowel movements without causing abdominal cramps. Its sweet taste and cold potency make it particularly suitable for Pitta-aggravated constipation with burning sensation. - Skin Health and Blood Purification
Aragvadha is classified as a premier kushtha (skin disease) remedy in Ayurveda. The bark, leaves, and fruit are used to manage chronic skin conditions including eczema, ringworm, scabies, psoriasis, and fungal infections. Its anti-inflammatory and blood-purifying action addresses the root pathology of most skin disorders in Ayurvedic understanding — accumulated toxins (ama) and impure blood. - Fever Management and Anti-pyretic Action
Amaltas has a cooling energy (Sheeta virya) that is highly effective in managing fever, particularly Pitta-type fever with burning sensation, excessive thirst, and inflammation. Classical Ayurvedic formulations for jwara (fever) frequently include Aragvadha. The bark decoction and leaf extracts help reduce body temperature while supporting the body’s recovery process. - Liver Health and Detoxification
The bitter compounds in Amaltas bark stimulate liver function, enhance bile secretion, and promote the elimination of accumulated toxins from the body. It is used in Ayurvedic treatment of jaundice (kamala), liver enlargement, and general liver weakness. Regular use of Amaltas preparations supports the liver’s natural detoxification capacity and protects liver cells from damage. - Cardiovascular and Metabolic Health
Amaltas supports cardiovascular health through its antioxidant and anti-inflammatory properties that reduce oxidative stress on the heart and blood vessels. Clinical observations suggest it helps regulate blood sugar levels by improving insulin secretion and sensitivity, supporting its traditional classification as a pramehaghna (anti-diabetic) herb. It also contributes to healthy cholesterol levels. - Antimicrobial and Wound Healing
Amaltas leaves and bark demonstrate significant antimicrobial activity against common bacterial and fungal pathogens. Topical application of leaf paste is used for managing skin infections, wounds, and inflammatory lesions. The astringent compounds promote tissue contraction and accelerate the healing process while preventing secondary infection.
How to Use Amaltas
| Form | Dosage | How to Take |
|---|---|---|
| Fruit pulp (fresh/dried) | 10–15 g once daily | Soak in warm water overnight; consume with warm water at bedtime for constipation relief |
| Amaltas churna | 3–5 g once daily | Mix with warm water or triphala; take after dinner for gentle overnight bowel cleansing |
| Bark decoction | 30–50 ml twice daily | Boil 10 g bark in 400 ml water; reduce to 100 ml; filter and drink warm for skin and fever |
| Leaf paste (topical) | As needed | Grind fresh leaves with water or coconut oil; apply to skin lesions, ringworm, or wounds |
Side Effects & Precautions
Amaltas is generally well tolerated, but its laxative effects mean overdose can cause loose stools, abdominal cramps, and diarrhoea. Its cooling properties mean that excessive consumption may worsen conditions related to cold (Vata and Kapha aggravation). Pregnant women should avoid Amaltas due to its strong laxative and potentially uterus-stimulating effects. People with low blood pressure or hypotension should use it cautiously. Those with chronic gastrointestinal conditions should consult an Ayurvedic physician before regular use.
Classical References
Aragvadha (Amaltas) is one of the most celebrated herbs in classical Ayurvedic texts. Charaka Samhita places it foremost among the kustha-hara (skin disease-curing) herbs and mentions it as a key herb in the Aragvadhadi mahakashaya — one of the 50 great formulation groups. Sushruta Samhita recommends it for kushtha (skin diseases), jwara (fever), vibandha (constipation), and krimi (parasitic conditions). Ashtanga Hridayam by Vagbhata uses Aragvadha prominently in virechana (purgation) therapy protocols and skin disease formulations. Bhavaprakasha Nighantu includes it in the Haritakyadi varga, noting its mild purgative, anti-skin disease, and fever-relieving properties.
