Purana Ghrita: The Ancient Science of Aged Ghee for Medicinal Use
While most people consume ghee fresh, ancient Ayurvedic physicians recognized something remarkable: ghee that is intentionally aged for years—even decades or centuries—transforms into one of the most powerful medicines in traditional Indian healing. This is Purana Ghrita, the 'old ghee' that Charaka Samhita calls superior to fresh ghee for treating serious diseases.
This guide explores the science and tradition behind aged ghee—from chemical transformations during aging to therapeutic applications for conditions like epilepsy and skin diseases. First, understand the complete Ayurvedic guide to ghee.
🕰️ Purana Ghrita Quick Facts
What Is Purana Ghrita? Understanding Aged Ghee
Purana Ghrita (पुरान घृत) literally translates to "old ghee" in Sanskrit. While modern consumers are trained to check expiry dates and discard "old" food, Ayurveda recognized that ghee is the exception to this rule—it actually becomes more medicinally potent with age.
The Charaka Samhita, written over 5,000 years ago, categorizes ghee by age and assigns different therapeutic properties to each:
| Age Category | Sanskrit Name | Primary Properties |
|---|---|---|
| Fresh (< 1 year) | Nava Ghrita | Nutritive, building (Brimhana), sweet |
| 1+ years old | Purana Ghrita | Therapeutic, digestive, lighter |
| 10+ years old | Dashvarsha Ghrita | Highly medicinal, anti-epileptic |
| 100+ years old | Kumbha Ghrita / Maha Ghrita | Extremely potent, rare, sacred |
🕉️ From the Charaka Samhita
"Purana Ghrita (old ghee) is Tikshna (penetrating), Ushna (warming in effect), and Lekhaniya (scraping/reducing). It cures Unmada (insanity), Apasmara (epilepsy), Murchha (fainting), poisoning, fever, and diseases of the ears, eyes, head, and female reproductive system."
Notice how the properties change from fresh ghee's "sweet, cooling, building" to aged ghee's "penetrating, warming, reducing"—a complete transformation.
How Aging Transforms Ghee: The Science
What happens chemically when ghee is aged for years? While modern research on Purana Ghrita is limited, traditional observations and preliminary studies suggest several transformations:
🔬 Chemical Transformations During Aging
Why Ghee Doesn't Spoil Like Other Fats
Most fats go rancid within months, but properly made ghee can last decades. The secret lies in its composition:
- Zero Moisture: Bacteria and mold require water—pure ghee contains less than 0.1% moisture
- No Milk Solids: The proteins and lactose that spoil in butter are completely removed
- Natural Antioxidants: Fat-soluble vitamins and butyric acid protect against oxidation
- Anaerobic Storage: Traditional earthen pots limit oxygen exposure
This is why proper ghee storage is critical—ghee made with higher moisture or stored improperly will indeed spoil rather than age beneficially.
Therapeutic Uses of Purana Ghrita
Classical Ayurvedic texts prescribe Purana Ghrita for conditions where fresh ghee would be contraindicated or insufficient. Here are the major therapeutic applications:
🧠 Neurological Disorders (Apasmara & Unmada)
The most famous use of Purana Ghrita is for epilepsy (Apasmara) and mental disorders (Unmada). Ancient texts describe 10-year-old ghee as specifically indicated for seizure disorders. The aged ghee is believed to penetrate the nervous system more effectively, calming aberrant electrical activity and nourishing damaged neural tissue. Modern practitioners continue to use Purana Ghrita as adjunct therapy for treatment-resistant epilepsy.
🌿 Chronic Skin Conditions (Kushtha)
Purana Ghrita is prescribed for stubborn skin diseases including psoriasis, chronic eczema, and vitiligo. Its Lekhaniya (scraping) quality helps remove accumulated toxins from skin tissues. Both internal consumption and external application are recommended. For skin conditions, aged ghee is often combined with bitter herbs in formulations like Panchatikta Ghrita.
👁️ Eye Diseases (Netra Roga)
Aged ghee is considered superior to fresh ghee for eye treatments (Netra Basti) and chronic vision problems. The warming, penetrating quality of Purana Ghrita is believed to dissolve accumulated Kapha and toxins in the eye tissues more effectively than fresh ghee's cooling nature.
🩹 Chronic Wounds (Dushta Vrana)
Non-healing wounds, old burns, and chronic ulcers benefit from Purana Ghrita's tissue-penetrating properties. The aged ghee is applied directly to remove necrotic tissue, stimulate granulation, and promote healing. This application has parallels to modern debriding agents.
🔥 Chronic Fevers & Toxicity
Purana Ghrita is indicated for Vishama Jwara (intermittent chronic fevers) and Visha (poisoning/toxicity). Its deep-penetrating nature helps extract toxins from tissues where fresh ghee, being nutritive, might actually nourish the pathology. This is why Ayurveda distinguishes carefully between when to use fresh vs. aged ghee.
Fresh Ghee vs. Aged Ghee: When to Use Which
Understanding when to use Nava Ghrita (fresh) versus Purana Ghrita (aged) is fundamental to Ayurvedic therapeutics:
| Aspect | Fresh Ghee (Nava) | Aged Ghee (Purana) |
|---|---|---|
| Primary Action | Building (Brimhana) | Reducing (Lekhaniya) |
| Energy | Cooling (Sheeta) | Warming (Ushna) |
| Best For | Nourishment, Vata/Pitta | Detoxification, Kapha |
| Weight Effect | Weight gain support | Weight reduction support |
| Daily Use | ✅ Recommended | ⚠️ Therapeutic only |
| Availability | Readily available | Rare, expensive |
⚠️ Important: Purana Ghrita is medicinal, not nutritional. For everyday cooking, general nourishment, and building tissues, fresh high-quality ghee is preferred. Aged ghee should be used under Ayurvedic practitioner guidance for specific therapeutic purposes. Using Purana Ghrita when fresh ghee is indicated (and vice versa) can produce opposite effects.
How to Prepare and Store Ghee for Aging
If you want to age ghee at home, the process requires meticulous attention to quality and storage conditions:
🏺 Traditional Ghee Aging Protocol
Step 1: Start with Superior Quality Ghee
- Use only traditional Bilona method ghee
- Source from grass-fed A2 indigenous cows (Gir, Sahiwal)
- Moisture content must be extremely low (<0.1%)
- No preservatives, additives, or adulterants
Step 2: Choose Appropriate Container
- Traditional: Earthen pot (matka) with lid—allows minimal air exchange
- Alternative: Brass or bronze vessel with tight seal
- Avoid: Plastic, aluminum, or any reactive metals
- Container must be completely clean and dry
Step 3: Storage Conditions
- Temperature: Cool, consistent (15-25°C ideal)
- Light: Complete darkness or minimal light exposure
- Location: Dry place, away from strong odors
- Duration: Undisturbed for intended aging period
Step 4: Monitoring (Annually)
- Check for any signs of contamination or mold
- Observe color change (should darken gradually to amber)
- Smell should intensify but not turn rancid or sour
- Texture may become more granular—this is normal
Realistic expectations: Home aging for 1-3 years is achievable with proper care. Genuine 10+ year Purana Ghrita is extremely rare and typically acquired from traditional Ayurvedic families, temples, or specialized practitioners who have maintained ghee across generations.
Common Myths About Aged Ghee
❌ Myth: "Old ghee is spoiled ghee and should be thrown away"
Reality: This applies to most fats but not ghee. Pure ghee lacks the moisture and proteins that cause spoilage. When properly made and stored, ghee undergoes beneficial aging rather than degradation. The key is starting with low-moisture, high-quality ghee and proper storage conditions. Purana Ghrita has been intentionally aged and valued for millennia in Ayurveda.
❌ Myth: "You can age any store-bought ghee to make Purana Ghrita"
Reality: Not all ghee is suitable for aging. Commercial ghee often has higher moisture content, may contain additives, or is processed in ways that compromise long-term stability. Only traditionally prepared ghee with extremely low moisture (<0.1%) from indigenous cow breeds is appropriate for intentional aging.
❌ Myth: "Purana Ghrita is better than fresh ghee for everything"
Reality: Fresh and aged ghee have opposite properties and different uses. Fresh ghee is building, nourishing, and cooling—ideal for daily consumption, children, and underweight individuals. Aged ghee is reducing, penetrating, and warming—best for specific therapeutic conditions. Using the wrong type for your condition can be counterproductive.
❌ Myth: "Claims of 100-year-old ghee are always fake"
Reality: While fraud exists, genuinely old ghee does exist in some traditional families, temples, and Ayurvedic institutions. Ghee has been passed down through generations, especially in priestly families where it was used for rituals. However, such Purana Ghrita is extremely rare and expensive. Be skeptical of commercial claims but do not dismiss the tradition entirely.

Frequently Asked Questions
What is Purana Ghrita and how is it different from regular ghee?
Purana Ghrita literally means "old ghee" in Sanskrit. While regular ghee is consumed fresh (within months of preparation), Purana Ghrita is intentionally aged for 1 to 100+ years under specific conditions. During aging, chemical transformations occur: the pH becomes more alkaline, fatty acid composition changes, and therapeutic compounds concentrate. Fresh ghee is primarily nutritional—Purana Ghrita becomes medicinal. The older the ghee, the more potent its healing properties. Ayurvedic texts describe aged ghee as Lekhaniya (scraping/reducing) rather than Brimhana (building), making it therapeutically different from fresh ghee.
How long should ghee be aged to become Purana Ghrita?
Ayurvedic texts categorize aged ghee by duration: 1-year-old ghee (Purana) has enhanced digestive properties. 5-year-old ghee is used for neurological conditions. 10-year-old ghee (Dashvarsha Ghrita) treats serious mental disorders and skin diseases. 100-year-old ghee (Kumbha Ghrita or Maha Ghrita) is considered extremely rare and powerful, historically reserved for treating intractable conditions like epilepsy and possession states. For general therapeutic use, 1-5 year aged ghee provides significant benefits. The therapeutic potency increases with age, but aged ghee becomes increasingly rare and expensive.
What conditions can Purana Ghrita treat according to Ayurveda?
Classical Ayurvedic texts prescribe Purana Ghrita for: Apasmara (epilepsy and seizure disorders), Unmada (mental disorders including schizophrenia), Vishama Jwara (chronic intermittent fevers), Kushtha (skin diseases including psoriasis and eczema), Shotha (inflammatory swelling), Visha (poisoning and toxicity), Vranas (chronic wounds that do not heal), and Netra Roga (eye diseases). The aged ghee is believed to penetrate deeper tissues, reduce inflammation more effectively, and balance doshas more powerfully than fresh ghee. It is particularly valued for conditions where fresh ghee is contraindicated or insufficient.
Can I age ghee at home to make Purana Ghrita?
Technically yes, but it requires specific conditions. Traditional requirements include: starting with highest quality ghee (A2 Bilona method, very low moisture), using appropriate containers (earthen pots, brass vessels, or specific copper containers—never plastic or reactive metals), storing in cool, dark place with consistent temperature (15-25°C), keeping container sealed but allowing minimal air exchange, and avoiding contamination over years. Most critically, the starting ghee must have extremely low moisture content (<0.1%). Home aging is possible for 1-3 years with proper care. However, genuine long-aged Purana Ghrita (10+ years) is typically acquired from traditional Ayurvedic families or specialized practitioners who have maintained ghee for generations.
Is Purana Ghrita safe to consume? Does old ghee go rancid?
Properly prepared and stored Purana Ghrita does NOT go rancid—this is a key distinction from other fats. Ghee is uniquely stable because it contains no moisture or milk solids (which cause spoilage in butter). When stored correctly, ghee undergoes beneficial chemical changes rather than degradation. Signs of properly aged Purana Ghrita: darker golden to amber color, more intense aroma, slightly different taste (less sweet, more complex), and thicker consistency. Signs of spoiled ghee (NOT proper Purana Ghrita): rancid or sour smell, moldy appearance, extremely dark (almost brown) color, or bitter taste. The key is starting with pure, low-moisture ghee and maintaining proper storage conditions throughout the aging process.
Conclusion: Ancient Wisdom for Modern Health
Purana Ghrita represents one of Ayurveda's most fascinating concepts—the idea that time itself can transform a nourishing food into a powerful medicine. While modern science is only beginning to investigate these claims, the tradition has persisted for millennia because practitioners observed real therapeutic effects.
For everyday use, fresh, high-quality ghee remains the recommendation. But knowing that ghee doesn't simply "expire" like other fats—that it can potentially grow more therapeutic with proper aging—deepens our appreciation for this remarkable substance that has sustained Indian civilization for thousands of years.
Whether you're interested in the therapeutic applications of aged ghee or simply want the best fresh ghee for daily nourishment, the starting point is always the same: authentic, traditionally prepared, A2 Bilona ghee from indigenous cows.
