## Key facts

- **Pharmacopoeia status:** Listed in Ayurvedic Formulary of India (AFI) Part I; described in Ayurvedic Pharmacopoeia of India (API); included in CCRAS clinical practice guidelines for Amavata (Rheumatoid Arthritis)

## Names and identification

| Language | Name |
|----------|------|
| English | Simhanada [Guggulu](/formulation/guggulu/)|Simhanada Guggulu |

## Where is it described in the classical texts?

Bhaishajya Ratnavali (Amavata Chikitsa Prakarana, Chapter 29); also described in Chakradatta (Amavata Chikitsa) and Yoga Ratnakara

## How does it work?

- DMARD-like action: The combined ingredients function as Disease Modifying Anti-Rheumatic Drugs, modulating immune response and preventing progressive joint destruction in rheumatoid arthritis
- Ama Pachana (toxin digestion): Shuddha [Gandhaka](/glossary/concepts-a-m/#gandhaka) (purified sulphur) and castor oil act synergistically to digest metabolic toxins (Ama) that are considered the root cause of Amavata in Ayurvedic pathology
- Anti-inflammatory and anti-gout: [Triphala](/herb/triphala/) provides potent [antioxidant](/reference/antioxidant/), anti-inflammatory, and anti-hyperuricemic effects; guggulsterones inhibit pro-inflammatory cytokine cascades
- Mild purgative detoxification: Castor oil ([Eranda](/herb/eranda/) Taila) provides gentle [laxative](/reference/laxative/) effect that eliminates accumulated Ama from the GI tract, breaking the Ama-Vata cycle
- Immunomodulation: [Guduchi](/herb/guduchi/) (Tinospora cordifolia) modulates both innate and adaptive immune responses, reducing autoimmune-mediated joint destruction

## Which traditional uses are supported by research?

- Rheumatoid arthritis (Amavata) management validated through multiple reviews confirming DMARD-like activity with significant reduction in inflammation, pain, and stiffness
- Anti-gout and anti-hyperuricemic activity validated through [Triphala](/herb/triphala/)'s demonstrated anti-hyperuricemic effects in pharmacological studies
- Joint flexibility improvement validated through clinical observations showing enhanced mobility and reduced swelling
- Detoxification and Ama elimination validated through the laxative and digestive mechanisms of castor oil and purified sulphur combination

## What do recent clinical trials show?



*3 further claims previously listed here could not be traced to a published paper and have been removed. Classical formulations are researched largely in journals that PubMed does not index, so an absence here reflects the reach of the index rather than the state of the evidence.*

## Recent safety updates

- Contains purified sulphur which may cause mild GI discomfort in some patients; castor oil component may cause loose stools; avoid in patients with diarrhea or irritable bowel syndrome; not recommended during pregnancy and lactation
