Aragvadha: Benefits, Uses & Dosage

If you need a laxative but dread the cramping and exhaustion that harsher purges bring, Aragvadha is the herb Ayurveda built its reputation for gentleness on. The Bhavaprakash Nighantu calls it the safest and mildest purgative in Ayurveda, gentle enough to be described as suitable for children and the elderly.

In English it is known as Golden Shower or Purging Cassia, and in Hindi as Amaltas. Its botanical name is Cassia fistula Linn. The tree is easy to recognise: it hangs with beautiful golden-yellow flowers, and its long pods, 30 to 60 cm in length, hold the black pulp that is used as medicine.

The classical texts gave it many Sanskrit names, recorded in the Sahasra Yoga drug index, among them Kritamala, Rajavriksha, Rogaghna and Vyadhighataka. The Charaka Samhita even names a whole chapter after it, the Aragvadhiya Adhyaya, which deals with external applications for skin disease.

What makes it distinctive

Aragvadha is sweet in taste (Madhura Rasa), cooling in potency (Sheeta Virya) and heavy and unctuous (oily) in quality (Guru, Snigdha Guna). It remains sweet after digestion (Madhura Vipaka), which is part of why it moves the bowels without the harshness of other purgatives.

It balances all three doshas: Vata, Pitta and Kapha. Its particular specialty is clearing excess Pitta, the hot dosha, from the intestines.

The Bhavaprakash Nighantu lists Aragvadha's actions as a mild purgative, a fever reducer, a heart tonic, a remedy for skin disease, and a herb that calms Pitta and balances all three doshas. Here is how those actions play out.

Gentle Bowel Clearing

Aragvadha's primary action is mild purgation (Mridu Virechana). The Sharangadhara Samhita uses it as its example of Sramsana, a mild purgative that moves stuck waste in the digestive tract downward without first digesting it.

Aragvadha (Cassia fistula) is a mild purgative.

Sharangadhara Samhita, Parishishtam, Chapter 1

Its sweet taste and heavy, unctuous qualities make it soft on the gut, and Ayurvedic practice pairs it with Haritaki as a laxative. Our knowledge graph links it with gas and flatulence and irritable bowel syndrome.

Liver Support

In its chapter on liver disorders (Yakrit Roga), the Sharangadhara Samhita recommends purgation using Aragvadha alongside Haritaki, Amla, rock salt and other herbs, as juice or powder or with castor oil (Eranda Taila).

Skin Conditions

The Charaka Samhita's Aragvadhiya Adhyaya lists Aragvadha with turmeric, neem and other herbs, mixed with ox-bile and mustard oil, as an external application for difficult skin diseases, ringworm, alopecia and papular eruptions. The Sushruta Samhita places it at the head of the Aragvadhadi Gana, a group of herbs named after it that also includes neem, Guduchi, Patola and Chirayita.

Today, Ayurvedic practice combines it with Manjishtha, neem and Kutki for inflammatory skin conditions such as eczema. It is also linked with athlete's foot and hair loss.

Fever

Aragvadha is listed as a fever reducer (Jwara hara). The Sushruta Samhita describes decoctions of the Aragvadha group with Pippali as destroyers of Kapha-type fever.

Heart

The Bhavaprakash Nighantu calls Aragvadha Hridya, a herb that is good for the heart, which is why it is linked with heart disease in the tradition. Any heart condition needs medical care first.

Metabolic Disorders

The Charaka Samhita includes Aragvadha in a decoction with Triphala, Patha, Saptaparna, Musta and Nimba that it says controls Madhumeha and related diseases. Madhumeha is a classical urinary disorder; anyone with blood sugar concerns needs medical care.

The medicinal part of Aragvadha is the black pulp inside the fruit pods. Classical texts also use it in decoctions (Kashaya), and the leaves and bark appear in external applications.

Combinations

• As a laxative: with Haritaki.
• Inflammatory skin conditions: with Manjishtha, neem and Kutki.
• Liver-focused purgation: the Sharangadhara Samhita combines it with Haritaki, Amla, rock salt and other herbs, or with castor oil.

Because it works by moving the bowels, start at the lower end of the range and adjust slowly. The goal Ayurveda describes is a comfortable, gentle clearance, not a strong purge.

Aragvadha has an unusually gentle reputation. The Bhavaprakash Nighantu calls it the safest and mildest purgative in Ayurveda, and no drug and herb interactions are known.

Pregnancy

Aragvadha has traditionally been used in pregnancy. Because it moves things downward through the body, it should still be used with caution and only under qualified guidance while pregnant.

Too Much of a Good Thing

It is still a purgative. Taking more than you need can loosen the bowels more than intended, so start low, stay within the usual 2 to 15 g per day range, and reduce the dose if stools become too loose.

When to See a Doctor

Persistent constipation, a change in bowel habits, abdominal pain, fever or any heart symptoms need a medical check. Aragvadha is a traditional support, not a replacement for diagnosis.

Aragvadha is usually weighed against other Ayurvedic laxatives and the herbs it shares formulas with.

Aragvadha's gentle reputation makes it one of the few purgatives the classical texts describe for vulnerable groups. Still, dosing for these groups is best set by a qualified practitioner.

Pregnancy & Nursing

Aragvadha has traditionally been used in pregnancy, but because it causes a downward movement it must be used with caution and only under qualified guidance. Our sources give no specific guidance for nursing, so check with your doctor first.

Children

The Bhavaprakash Nighantu describes Aragvadha as suitable for children, a rare statement for a purgative. The sources do not give a children's dose, so ask a practitioner or pediatrician for one.

Elderly

The same text calls it suitable for the elderly. Its sweet taste and heavy, unctuous qualities make it gentler on the gut than harsher purgatives, which matters for older adults.

Athletes

Our sources give no athlete-specific guidance. Its role in Ayurveda is gentle bowel clearing and Pitta balance, not performance.
