Shata Dhauta Ghrita: The Scientific Breakdown of 100x Washed Ghee
For thousands of years, Ayurvedic practitioners have claimed that washing ghee 100 times transforms it into a miraculous healing cream. Modern skeptics dismissed it as pseudoscience—until researchers started testing it in laboratories.
What they found was remarkable: the ancient process of Shata Dhauta Ghrita (literally "hundred-times washed ghee") isn't mystical at all. It's sophisticated pharmaceutical chemistry disguised as a kitchen ritual. The repeated washing triggers molecular transformations that modern cosmetic science is only now beginning to replicate with expensive technology.
This comprehensive scientific analysis examines the peer-reviewed research, molecular chemistry, clinical trials, and laboratory data behind this viral Ayurvedic preparation.

Always start with pure, tested ghee for scientifically valid results.
The Chemistry of Fat Hydrolysis: What Actually Happens
At its core, the Shata Dhauta Ghrita process is enzymatic hydrolysis—the same reaction used in industrial soap-making and biodiesel production. But unlike industrial processes that use heat and chemical catalysts, this Ayurvedic method achieves it through mechanical action and time.
🔬 The Chemical Reaction
When water and ghee are rubbed together repeatedly, the following occurs:
- Ester Bond Cleavage: Triglyceride molecules (the main component of ghee) have three fatty acid chains attached to a glycerol backbone. Water molecules attack these ester bonds, breaking them apart.
- Emulsification: The mechanical shear force from rubbing creates tiny fat droplets suspended in water—a stable oil-in-water emulsion.
- Surface Area Expansion: A single wash can increase surface area by 10-15%. By the 100th wash, total surface area increases approximately 100-fold.
- Particle Size Reduction: Fat globules shrink from 50-100 micrometers to 1-5 micrometers, enabling dermal penetration.
Thermodynamics of the Transformation
Research published in the Journal of Pharmaceutical Science analyzed the energy changes during the washing process. Each wash cycle requires approximately 0.5-1.0 kJ of mechanical energy. This energy input overcomes the activation barrier for hydrolysis without requiring high temperatures that would damage bioactive compounds in ghee.
The process is endergonic (requires energy input), which explains why it cannot happen spontaneously and must be repeated many times. The cumulative effect of 100 washes provides enough energy to transform approximately 60-70% of the triglycerides into diglycerides, monoglycerides, and free fatty acids.
Clinical Research Evidence: What Studies Actually Show
Shata Dhauta Ghrita has been studied in multiple clinical trials, primarily in India where Ayurvedic research is well-funded. Here's what peer-reviewed science says:
Burn Wound Healing Studies
A 2018 randomized controlled trial at the Department of Ayurveda, BHU (Banaras Hindu University) compared Shata Dhauta Ghrita with silver sulfadiazine (the gold standard burn treatment) in 60 patients with second-degree burns.
| Parameter | Shata Dhauta Ghrita | Silver Sulfadiazine |
|---|---|---|
| Complete Healing Time | 14.2 ± 2.1 days | 16.8 ± 3.4 days |
| Pain Reduction (Day 3) | 73% reduction | 58% reduction |
| Scar Formation | 23% of cases | 41% of cases |
| Infection Rate | 6.7% | 3.3% |

Anti-Inflammatory & Skin Penetration Research
A 2020 study using confocal Raman microscopy tracked the penetration depth of fluorescently-labeled fatty acids in washed ghee preparations. Results showed:
- Standard moisturizer: Penetration limited to stratum corneum (0.1-0.3mm depth)
- Regular ghee: Moderate penetration into upper epidermis (0.3-0.5mm)
- Shata Dhauta Ghrita: Deep penetration into papillary dermis (1.2-1.8mm)
The researchers attributed this to the drastically reduced particle size and the biphasic (oil-water) nature allowing passage through both lipid and aqueous skin layers. This validates the Ayurvedic claim of penetrating "all seven layers of skin" (Sapta Dhatu).
📊 Key Research Finding
"The nano-emulsion structure of 100-times washed ghee demonstrated a 4.8-fold increase in transdermal delivery compared to non-washed ghee, with significant reduction in inflammatory markers (IL-6, TNF-α) in ex-vivo skin models."
- International Journal of Pharmaceutical Sciences and Research, 2020
The Copper Catalyst: More Than Tradition
Ayurvedic texts insist on using a copper vessel (tamra patra) for preparing Shata Dhauta Ghrita. Modern analysis reveals this isn't superstition—it's chemistry.
Copper Ionization Process
When ghee is rubbed against copper under mechanical pressure, a phenomenon called tribochemical reaction occurs. The friction generates localized heat (30-40°C) and pressure that causes copper atoms on the surface to oxidize and release Cu²⁺ ions into the emulsion.
Analysis by atomic absorption spectroscopy shows properly prepared Shata Dhauta Ghrita contains 0.5-2.0 ppm (parts per million) of copper. This trace amount provides:
- Antimicrobial Activity: Copper ions disrupt bacterial cell membranes, providing natural preservation
- Collagen Synthesis: Copper peptides activate lysyl oxidase, essential for collagen cross-linking
- Antioxidant Enhancement: Copper acts as a cofactor for superoxide dismutase (SOD), a powerful antioxidant enzyme
- Catalytic Effect: Accelerates the hydrolysis reaction by 2-3x compared to glass or steel vessels
Safety Profile of Copper Content
The WHO recommends a daily copper intake of 0.9-1.3 mg for adults. A typical application of 2-3 grams of Shata Dhauta Ghrita delivers only 1-6 micrograms of copper topically—far below systemic absorption thresholds and well within safe ranges for dermal application.
Molecular Structure Comparison: Before and After
Gas chromatography-mass spectrometry (GC-MS) analysis reveals dramatic changes in the fatty acid profile during the washing process:
| Component | Regular Ghee | 50x Washed | 100x Washed |
|---|---|---|---|
| Triglycerides | 96-98% | 55-60% | 28-32% |
| Diglycerides | 1-2% | 18-22% | 32-38% |
| Free Fatty Acids | 0.5-1% | 12-16% | 22-28% |
| Water Content | 0.1-0.3% | 8-12% | 18-24% |
| Particle Size (μm) | 50-100 | 5-15 | 1-5 |

The "Cooling Virya" Transformation: Scientific Explanation
Ayurveda classifies ghee as having "heating potency" (Ushna Virya), while Shata Dhauta Ghrita is described as "cooling" (Sheeta Virya). Modern thermal analysis provides a scientific basis for this claim.
Regular ghee has a melting point of 32-35°C (close to body temperature), meaning it absorbs heat when applied topically to melt. The washed preparation, however, is already in an emulsified state and doesn't require this phase transition. Additionally, the high water content (18-24%) provides evaporative cooling as moisture gradually evaporates from the skin surface.
Infrared thermography studies show a 0.8-1.2°C reduction in skin surface temperature within 5 minutes of applying Shata Dhauta Ghrita—validating the "cooling" sensation reported by users and described in classical texts.
✅ Scientific Validation of Traditional Claims
- "Penetrates seven skin layers" = Confirmed via confocal microscopy (1.2-1.8mm penetration)
- "Cooling property" = Validated by thermal imaging (0.8-1.2°C reduction)
- "Heals burns faster" = Clinical trials show 15% faster healing vs. modern treatments
- "Reduces scarring" = 44% less scar formation in controlled studies
Quality Matters: Why Purity is Critical for Valid Results
Here's where modern research and traditional wisdom perfectly align: the quality of the base ghee determines everything.
Studies attempting to replicate preparation using adulterated or low-quality ghee showed dramatically inferior results. A 2021 comparative study tested three ghee sources:
- Pure A2 Cow Ghee (Bilona method): Successfully formed stable white emulsion with proper texture and therapeutic properties
- Commercial mixed ghee (A1 + vegetable oil): Failed to emulsify properly, separated quickly, rancid smell developed within days
- Buffalo ghee: Formed emulsion but with different fatty acid profile and lower therapeutic markers
The researchers concluded that the specific fatty acid composition of A2 cow ghee, particularly its higher conjugated linoleic acid (CLA) and omega-3 content, is essential for proper hydrolysis and emulsion stability.

Several research institutions in India have ongoing trials examining these questions, with results expected in the next 2-3 years.
Frequently Asked Questions
Is there scientific evidence for Shata Dhauta Ghrita's effectiveness?
Yes. Multiple peer-reviewed studies have documented Shata Dhauta Ghrita's efficacy. A 2018 clinical trial published in the Journal of Ayurveda and Integrative Medicine showed significant improvement in burn healing with application of washed ghee preparations. Research from Banaras Hindu University demonstrated enhanced skin penetration and reduced inflammation markers. The process of fat hydrolysis and emulsification is well-documented in pharmaceutical science, validating the traditional Ayurvedic preparation method.
What happens at the molecular level during the washing process?
During the washing process, large triglyceride molecules undergo hydrolysis - the breaking of ester bonds by water. Each wash creates mechanical shear force that splits these molecules into smaller units (diglycerides, monoglycerides, and free fatty acids). The process also creates a stable oil-in-water emulsion where microscopic fat droplets are suspended in water. This increases surface area by approximately 100-fold, allowing the preparation to penetrate deeper skin layers. The transformation from lipophilic (fat-loving) to hydrophilic (water-loving) is what enables the 'cooling' property described in Ayurveda.
Why is copper vessel essential from a chemistry perspective?
Copper acts as a heterogeneous catalyst in the hydrolysis reaction. When ghee is rubbed against copper, trace amounts of copper ions (Cu²⁺) are released through mechanical friction. These ions accelerate the emulsification process and are incorporated into the cream, providing antimicrobial properties. Research shows copper peptides stimulate collagen and elastin production in skin cells. Additionally, copper has natural antibacterial properties, acting as a preservative in the water-containing emulsion. Studies measure approximately 0.5-2 ppm copper content in properly prepared Shata Dhauta Ghrita, which is within safe therapeutic ranges.
How does washed ghee penetrate '7 layers of skin' as claimed in Ayurveda?
Modern dermatology recognizes skin has multiple structural layers. The hydrolysis process reduces fat particle size from 50-100 micrometers to 1-5 micrometers, small enough to penetrate beyond the stratum corneum into the epidermis. The oil-in-water emulsion structure allows it to pass through both lipophilic cell membranes and hydrophilic intercellular spaces. Research using confocal microscopy has tracked labeled fatty acids from washed ghee preparations penetrating into the dermis layer (approximately 1-2mm deep), which aligns with Ayurveda's '7 layer' concept. Standard commercial moisturizers typically only penetrate 0.1-0.3mm.
