1. Abstract
Giloy (Tinospora cordifolia) an esteemed herb in Ayurvedic medicine, is recognized for its immunomodulatory, antipyretic, and anti-inflammatory activities. This review examines the standardized extract of Giloy in terms of its phytochemical composition, molecular mechanisms, and clinical applications in immune regulation, metabolic health, and inflammatory disorders. Key constituents include alkaloids, diterpenoids, and polysaccharides, which contribute to its adaptogenic and hepatoprotective effects. The paper also outlines therapeutic dosages, routes of administration, and safety profiles. As global interest in immune resilience and natural remedies rises, Giloy stands out as a potent phytopharmaceutical worthy of expanded clinical exploration.
2. Introduction
Giloy also known as Guduchi is a climbing shrub native to tropical India, widely revered in Ayurveda as a “Rasayana” or rejuvenative tonic. Traditionally prescribed for fever, chronic inflammation, and metabolic imbalance, Giloy has earned modern recognition for its ability to modulate immune responses and support systemic detoxification. Standardized extracts rich in bioactive markers are now being used in nutraceutical formulations aimed at enhancing resilience to infections and stress-induced physiological dysfunctions.
3. Composition and Mechanism of Action
Composition:
Standardized Giloy extract contains:
- Alkaloids (e.g., berberine, palmatine, tinosporine) – Antimicrobial and adaptogenic properties [1]
- Diterpenoid lactones (e.g., tinosporide, cordifolide) – Immunomodulatory and hepatoprotective action [2]
- Glycosides and Polysaccharides – Support immune regulation [3]
- Phenolics and Flavonoids – Antioxidant defense [4]
Mechanism of Action:
- Immunomodulation: Enhances macrophage activity, T-cell proliferation, and phagocytosis, strengthening both innate and adaptive immunity [5]
- Antipyretic and Anti-inflammatory: Inhibits COX-2 and downregulates pro-inflammatory cytokines (IL-1β, TNF-α) [6]
- Antioxidant Action: Scavenges free radicals, protecting tissues from oxidative stress [4]
- Hepatoprotective Effects: Stabilizes liver enzymes and prevents hepatocellular damage [7]
- Metabolic Regulation: Exhibits anti-diabetic and lipid-lowering effects via modulation of insulin sensitivity and lipid metabolism [8]
4. Clinical Benefits
Immune Enhancement
- Improves response to recurrent infections and allergic conditions [5]
- Enhances resistance during seasonal changes and post-illness recovery
Fever and Inflammation Management
- Traditionally used to manage dengue, chikungunya, and viral fevers with evidence of antipyretic efficacy [6]
- Reduces joint pain and systemic inflammation in arthritis models
Liver and Detoxification Support
- Supports liver enzyme normalization in cases of drug-induced hepatotoxicity [7]
- Promotes detoxification and bile secretion
Metabolic and Diabetic Support
- Reduces fasting blood glucose and improves insulin sensitivity in type 2 diabetes models [8]
- Shows potential for adjunctive use in metabolic syndrome
Stress and Cognitive Function
- Exhibits adaptogenic properties that reduce anxiety and support memory retention [9]
4. Dosage & Administration
Oral Consumption:
- Capsules/Tablets: 300–500 mg of standardized extract (with 2–5% bitters or alkaloids) twice daily
- Juice/Satwa (Aqueous Extract): 10–15 ml once or twice daily
- Powder (Churna): 1–3 grams daily with warm water or honey
Duration:
- Effective in both short-term infections and long-term immune modulation (4–12 weeks)
Note: Clinical supervision is recommended, especially in autoimmune or immunocompromised individuals.
5. Safety & Considerations
- Hypoglycemia Risk: May potentiate anti-diabetic medications; monitor blood glucose
- Autoimmune Conditions: Use cautiously in individuals with RA, lupus, or similar conditions due to immune stimulation
- Pregnancy & Lactation: Limited human data; not advised without professional guidance
- Pediatric Use: Generally safe in lower doses; aqueous extracts preferred under supervision
6. Discussion
Giloy offers a powerful combination of immune enhancement, anti-inflammatory activity, and metabolic support, all within a safe and well-tolerated botanical framework. Its adaptogenic potential and ability to regulate both immunity and detoxification pathways make it an ideal agent in both preventive and therapeutic wellness protocols. Future trials are essential to validate standardized dosing and long-term efficacy across different patient populations.
7. Conclusion
Standardized Giloy extract is a clinically promising botanical with broad-spectrum applications in immunity, detoxification, and chronic inflammation. Its well-characterized phytoconstituents, immunomodulatory action, and safety profile position it as a valuable addition to modern herbal pharmacology. Rational use under medical guidance can optimize its outcomes and contribute to holistic health strategies.
