Amaltas is the dried pulp of the ripe pods of Cassia fistula, a widely distributed Indian tree known for its cascading yellow flowers and long, cylindrical seed pods.

Botanical identity and part used

Amaltas belongs to the Fabaceae family, in the Caesalpinioideae subfamily, alongside tamarind and gulmohar. The tree is deciduous, flowering in bright yellow racemes through the summer months.

The commercially recognised drug is the pulp inside the mature pod, separated from seeds, septa and pod wall. Bark, leaf and flower are used separately in specific classical formulations and are not part of the standard pulp specification.

Where it grows in India

Cassia fistula grows across much of India in dry deciduous forest and as a widely planted avenue tree, with organised collection concentrated in the forest tracts of Madhya Pradesh, Chhattisgarh, Maharashtra and adjoining central Indian states. It is also cultivated ornamentally through the north and south of the country.

Much of the commercial pulp entering trade is collected as minor forest produce from wild and semi-wild trees rather than grown as a dedicated field crop.

Harvest and processing

Pods form after the summer flowering and take roughly six to nine months to mature, darkening from green to a hard blackish-brown shell as they ripen. Fully ripe pods are collected, typically through the winter months, once the pulp inside has set.

Pods are cracked open along their length, and the sticky, dark pulp is separated from the seeds and internal partitions. The pulp is then sun-dried and either sold in lump form or ground into powder.

Why buyers source it

The pulp's activity is attributed to anthraquinone derivatives, principally rhein and sennoside-type glycosides along with aloe-emodin, present at roughly 2 per cent in dried pulp by classical estimates. This anthraquinone content is the basis of Amaltas's long-standing use as a mild laxative ingredient.

Buyers checking quality look for pulp free of mould and fermentation odour, since the pulp is prone to souring in humid storage, and for a low proportion of adhering seed and pod-wall fragments.

Forms that trade

AV Biotech supplies Amaltas as deseeded dried pulp and milled pulp powder. Bark and leaf material for specific classical formulations can be sourced separately on request.

Industry applications of Amaltas

Amaltas pulp moves mainly into Ayurvedic and mild-laxative pharmaceutical manufacturing, with smaller volumes into nutraceutical and veterinary use.

Ayurvedic and pharmaceutical manufacturing

Classical units buy deseeded pulp for churna, avaleha and syrup-based formulations positioned around mild, gentle bowel regularity, particularly in paediatric and geriatric-oriented products. This remains the largest single use of the material.

Pharmaceutical buyers producing over-the-counter mild-laxative syrups and confections also draw on standardised pulp extract.

Nutraceutical and functional food brands

Some regional functional-tea and wellness-drink formulators use Amaltas pulp for its traditional gentle-digestive positioning, generally in blended rather than single-ingredient products.

Herbal and traditional confectionery

Pulp is used in traditional sweetened confections and lehyam-style preparations in parts of South and Central Asia, where the natural sweetness of ripe pulp is part of the appeal.

Veterinary use

Small quantities of pulp are used in traditional veterinary preparations for livestock digestive complaints, generally in combination with other herbs.

Cosmetic and dye-adjacent use

Bark and pod material see limited use in natural-dye and tanning-adjacent applications, separate from the pharmaceutical pulp trade.

Quality pitfalls buyers should check for

Because Amaltas pulp is naturally sticky and moisture-retentive, poorly dried lots are prone to fermentation and mould during transit, especially in humid conditions. Buyers should check for a sour or fermented odour and reject lots showing visible mould before accepting delivery.

Adhering seed coat and pod-wall fragments left in from incomplete deseeding reduce effective pulp content, so a stated foreign-matter limit and a visual sample check are worth confirming on first orders.

Export and regional trade

Beyond India, Amaltas pulp moves into Southeast and South Asian markets that share a similar traditional-medicine and confectionery use pattern, including Thailand's laxative-pill manufacturing sector. Buyers in these markets typically specify the same deseeded, low-moisture pulp grade used domestically.

Common product formats

• Ayurvedic churna and avaleha formulations for digestive regularity
• Mild-laxative syrups and paediatric formulations
• Functional tea and wellness-drink blends
• Traditional sweetened pulp confections
• Veterinary digestive-support preparations

Traditional use and current research

Amaltas is described in Ayurveda under the Sanskrit name Aragvadha and is classed among mild purgative (Bhedaniya) dravyas. It has a long folk-medicine record across South Asia for gentle digestive support.

The following notes describe traditional positioning and published research directions, not established medical outcomes.

Digestive regularity

The pulp's traditional and best-documented use is as a mild, gentle laxative, attributed to its anthraquinone glycoside content. It has historically been considered gentle enough for use in children and the elderly compared to stronger purgative herbs.

Traditional fever and skin-related use

Classical and folk sources describe Amaltas bark, leaf and pulp preparations used traditionally in fever management and for topical application to skin conditions. Controlled clinical evidence for these uses remains limited.

Antioxidant and metabolic research interest

Laboratory studies on Cassia fistula pod extracts have reported antioxidant activity and preliminary findings related to blood-sugar and mineral content. These are early research directions, not confirmed clinical outcomes.

Antimicrobial research

Extracts of the pulp and pod have been studied for activity against selected microorganisms in laboratory settings. This supports further research rather than a therapeutic claim on a finished product.

Traditional cardiotonic and general wellness use

Some classical sources describe Amaltas being used as a mild general tonic in combination formulations, alongside its better-known laxative role. This is a minor traditional use compared to its digestive application and is rarely the basis of a standalone product today.

What buyers should note on claims

Because Amaltas's laxative activity depends on anthraquinone content, and that content varies with pod ripeness and storage, formulators should confirm assay on each batch used for claim substantiation rather than relying on generic literature values, and pulp condition should be checked on the current shipment rather than assumed from an earlier one.
