Overview
Kareel® — Natural Dye & Mordant from Terminalia Chebula, Developed for Industrial Dyeing
Myrobalan Dye & Natural Mordant for Cotton — Bulk Supply from India
AMA Herbal manufactures and exports natural textile dyes from Lucknow, India, and has been working with mills and dyeing houses since 1996. Kareel® is the company's natural dye and natural mordant, produced from Terminalia chebula — the Myrobalan fruit — which has historically been used across South Asia both to dye cotton and to prepare fibre ahead of a second natural dye. The extract works on cotton and plant fibres, and is produced at a scale that supports regular bulk orders.
As a natural dye manufacturer in India, AMA Herbal processes each batch under controlled conditions and provides technical data sheets, shade references, and application guidance for dyeing houses evaluating Kareel® for the first time. See also Bee® — a catechu-based natural brown dye also available from AMA Herbal.
For textile mills and garment manufacturers sourcing natural dyes and mordants for bulk production, Kareel® is available with standard export documentation, consistent shade batches, and direct technical support from the production team. AMA Herbal also assists with shade development and small-batch sampling before mills commit to larger orders.
"Terminalia chebula has been used in dyeing and mordanting across the subcontinent for centuries. Kareel® is our effort to make that same source material available to modern mills — consistently processed, properly documented, and export-ready — without the inconsistencies that have historically made natural dyes difficult to work with at scale."
AMA Herbal — Natural Dye Manufacturer, India, since 1996Raw Material
Source: Terminalia chebula — Myrobalan Fruit
Kareel® is derived from Terminalia chebula — the Myrobalan fruit — which is naturally high in tannin, the compound responsible for both its dyeing behaviour and its mordanting action. The dye performs well on cotton and other plant-based fibres, where tannin binds readily to cellulose. Used on its own, Kareel produces greenish-yellow, khaki, and grey shades; used as a pre-treatment, it improves colour uptake and fastness for a second natural dye applied afterward.
AMA Herbal sources Terminalia chebula fruit domestically and processes it through a consistent extraction and refining sequence. Each production batch is checked for tannin content and shade consistency before dispatch, and reference shade cards are available for mills comparing batches or running shade approvals.

Applications
Suitable for Cotton & Plant Fibres — Dyeing and Mordanting
Kareel® is used in dyeing houses and fabric processors working with cotton and plant-based fibres. It is compatible with the main industrial application methods and does not require special equipment beyond what mills already use for other natural dyes. Shade depth depends on fibre preparation, mordant, and process conditions.
| Fibre / Substrate | Notes |
|---|---|
| Cotton | Primary substrate; strong tannin affinity gives consistent greenish-yellow and khaki shades |
| Plant Fibres | Good uptake on cellulosic plant fibres with comparable binding behaviour to cotton |
| Woven Fabric & Yarn | Suitable for fabric roll and hank-form yarn dyeing ahead of weaving or knitting |
| Synthetic Fibres | Not suitable — polyester and nylon lack the tannin-binding sites Kareel requires |

Background
What is Natural Red Dye for Fabric?
Natural Red Dye — a Brief Overview
Natural red dyes for textile use are colorants extracted from biological sources — insects, plant roots, or bark — that produce red and crimson shades on fabric without synthetic chemistry. Historically, the main sources have been lac (Kerria lacca), madder root (Rubia tinctorum), and some botanical extracts. They are used as alternatives to synthetic azo red dyes in applications where brands or mills are working to reduce chemical inputs, meet eco-certification criteria, or respond to buyer requirements for natural-origin products.
Nimbus® is AMA Herbal's lac-based red, extracted from Kerria lacca. For madder-based red, see Rubia® natural red dye. Both are available for evaluation and bulk supply.

Manufacturing Expertise Behind Nimbus®
AMA Herbal has been manufacturing natural dyes since 1996, working from its own production facility in Lucknow, India. Nimbus® draws on that history — sourcing Kerria lacca from established domestic suppliers, then running it through a consistent extraction and refining sequence rather than a one-off process that varies batch to batch.
Production controls matter more than the raw material itself in a category like lac dye, where natural variation in the source stick can otherwise show up as shade drift. Our team checks each batch against reference shade cards before it's approved for dispatch, and keeps records so a mill reordering months later can expect the same result they got the first time.
Laboratory validation happens before larger runs — new mills evaluating Nimbus® typically start with a lab sample and application trial on their own equipment, which is where mordanting and pre-treatment questions for cotton usually get resolved. Our technical team works through that process directly rather than leaving it to a distributor.
For bulk orders, the same production line that runs sampling also handles industrial volume, so the shade a mill approves at sample stage is the shade they receive at scale. Export documentation is prepared alongside production, not as an afterthought.
