International Studies on Herbal, Natural-Dyed & Bioactive Textiles
The scientific study of plant-based functional textiles extends well beyond the traditional Indian concept of Ayurvastra.
International researchers commonly use terms such as bioactive textiles, functional textiles, antimicrobial natural dyes and plant-extract-treated textiles.
The central research question is remarkably similar:
Can plant-derived compounds provide textiles with measurable functions beyond colour?
Research from different countries and international journals is increasingly investigating this question through textile chemistry, microbiology, material science and standardized laboratory testing.

2026: A Systematic Review of 389 Research Records
One of the strongest recent additions to this field is the 2026 systematic review:
“Plant Extracts as Antibacterial and Antifungal Agents in Medical Textiles: A Systematic Review of Key Components, Efficacy, and Application Techniques.”
Researchers used Scopus and Web of Science and followed PRISMA methodology.
The process began with:
389 research records
After applying the study's eligibility criteria:
38 studies were included in the systematic review.
The researchers examined:
Plant Sources • Active Components • Extraction Methods • Textile Substrates • Application Techniques • Target Microorganisms • Antibacterial Activity • Antifungal Activity • Post-Laundering Durability
The review also found sustained growth in scientific publications in this area between 2020 and 2025.
Among the prominent plants identified was Aloe barbadensis – Aloe Vera.
Cotton was among the most important textile substrates examined.
Importantly, the review also found that results vary according to the plant material, extraction method, textile structure, application technique, concentration, temperature and processing conditions.
2025: Turmeric Was Actually Dyed onto Fabric and Tested
A 2025 study published in Green Technologies and Sustainability provides a particularly clear example of botanical-dye research.
Researchers extracted natural colour from:
Curcuma longa – Turmeric
and applied it to:
Cotton • Wool • Polyester
Different mordants and dyeing methods were investigated.
Researchers then measured:
Washing Fastness • Rubbing Fastness • Light Fastness • Colour Characteristics • Antimicrobial Activity
The finished turmeric-dyed textile samples were tested against:
Staphylococcus aureus
Proteus mirabilis
Pseudomonas aeruginosa
The researchers reported that the turmeric-dyed fabric samples demonstrated moderate antimicrobial activity.
This distinction is important.
The researchers were not simply demonstrating that Turmeric itself possesses certain characteristics.
They dyed actual textile materials with turmeric and subsequently tested the resulting textiles.
2023: Natural Dyes as Bioactive Textile Materials
A major 2023 review published in Environmental Science and Pollution Research examined the development of bioactive textile materials using natural dyes.
The review identified research into natural dyes providing functions including:
Antimicrobial Activity
UV Protection
Insect Repellency
The researchers examined the effects of natural dyes on both natural and synthetic fibres.
Their review reflects a broader shift in textile research:
Natural Dye = Colour + Potential Functional Characteristics
rather than:
Natural Dye = Colour Only
The researchers also emphasized the need for continued work on bioactivity, biocompatibility and sustainability.
2015: Turmeric Used in Antimicrobial Fabric Development
A study published in Industrial Crops and Products investigated natural dyes extracted from:
Curcuma longa – Turmeric
Trigonella foenum-graecum – Fenugreek
Nerium oleander
Researchers compared different extraction techniques including:
Aqueous • Acidic • Alcoholic • Alkaline
Turmeric dye prepared using aqueous extraction demonstrated antibacterial activity.
The researchers subsequently used the antimicrobial properties of the natural dyes in developing antimicrobial fabric.
This research also demonstrates why extraction methodology matters: the same botanical material can behave differently depending on how its compounds are extracted and processed.
2013: Multiple Natural Dyes Tested on Cotton
Research published in the Bangladesh Journal of Scientific and Industrial Research investigated cotton fabrics dyed using multiple botanical materials, including:
Pomegranate • Wild Mangosteen • Myrobalan • Arjun • Betel Nut • Onion • Tea • Neem • Eucalyptus • Dye Flower
The fabrics were evaluated against:
Bacillus subtilis
Escherichia coli
Several naturally dyed fabrics demonstrated antimicrobial activity at varying levels.
The study also evaluated wash fastness, making it useful for understanding the relationship between natural dyeing, textile performance and functional properties.
2009: Aloe Vera Applied Directly to Cotton
An experimental study published in the African Journal of Microbiology Research investigated:
Aloe Vera Gel Extract + Cotton Fabric
The research was conducted through the Textile Engineering Department at Bahir Dar University, Ethiopia.
Researchers evaluated Aloe Vera-treated cotton for antimicrobial activity against:
Staphylococcus aureus
The importance of this study lies in the fact that the botanical material was applied to cotton fabric and the treated textile was experimentally evaluated.
It therefore provides another example of researchers moving from:
Plant → Extract → Textile → Laboratory Testing
What International Research Is Showing
Across these studies, a common scientific pathway emerges:
Plant / Botanical Source
↓
Extraction of Natural Compounds
↓
Application to Textile Fibre
↓
Dyeing / Functionalisation
↓
Fixation / Interaction with Fibre
↓
Laboratory Testing
↓
Measurement of Functional Properties
↓
Durability / Washing Evaluation
Researchers are therefore not simply assuming that because a plant possesses a particular property, a textile coloured with that plant automatically possesses the same property.
Instead, modern studies ask:
Which plant?
Which part of the plant?
Which extraction method?
Which concentration?
Which textile fibre?
Which mordant or fixation method?
Which microorganism?
Which standardized testing method?
How much activity remains after washing?
These questions are transforming botanical textiles from an area based largely on traditional knowledge into an increasingly measurable field of functional textile science.
Different Terminology, Similar Scientific Curiosity
India's Ayurvastra tradition approaches herbal textiles through Ayurveda, botanical knowledge, natural fibres and traditional textile practices.
International researchers more commonly describe related developments as:
Bioactive Textiles
Functional Textiles
Plant-Extract-Treated Textiles
Antimicrobial Natural Dyes
Biofunctional Textile Finishes
The terminology is different, but the scientific question remains remarkably similar:
Can botanical materials give textiles useful characteristics beyond colour?
The expanding international research literature suggests that, under appropriate processing conditions, certain plant-derived extracts and natural dyes can impart measurable functional properties to textile materials.
And perhaps that is where ancient botanical knowledge and modern textile science meet most interestingly:
Nature provides the material.
Science measures what remains in the textile.
