Manjistha
Rubia cordifolia L.
Manjistha (Rubia cordifolia L.) is a climbing perennial vine native to the Indian subcontinent, valued for over two thousand years as Ayurveda's foremost blood purifier — and now attracting growing scientific scrutiny for its wide-ranging pharmacological properties.
Its roots — characterised by a distinctive rusty-red bark — are the primary medicinal part, containing more than 100 bioactive compounds including anthraquinones, triterpenoids, cyclic hexapeptides, flavonoids and polysaccharides. 1
At a Glance — Key Evidence-Backed Benefits
Traditional Ayurvedic Uses
The Charaka Samhita, Sushruta Samhita, and Ashtanga Hridayam all cite Manjistha prominently, classifying it within the Varnya group (complexion-enhancing herbs) and as a core remedy for disorders arising from vitiated blood (rakta dushti). 3
Ayurvedic Properties (Guna)
How It Was Traditionally Administered
Practitioners administered Manjistha in decoction (kwath) form for skin diseases, menstrual disorders, jaundice, urinary complaints, fever, and inflammatory joint conditions. 34 Externally, the powdered root was applied as a paste to wounds and skin eruptions, while medicated oils were used in therapeutic massage to improve circulation and reduce swelling.
Classical Formulations
- Manjishtadi Kwath — decoction for chronic skin diseases and blood disorders
- Mahamanjishtadi Kashaya — stronger compound decoction for persistent inflammation
- Manjistha Churna — powder taken internally or applied as a face mask (ubtan)
- Manjishtadi Taila — medicated oil applied to wounds, ulcers, and skin conditions
- Raktashodhakarishta — fermented tonic for blood purification
What the Research Says
A landmark 2022 comprehensive review published in Frontiers in Pharmacology confirmed that R. cordifolia harbours more than 100 phytochemical compounds and exhibits broad pharmacological activities in both in vitro and in vivo models. 1 The majority of studies to date are preclinical; robust human clinical trials remain limited.
Extracts administered at 100–300 mg/kg in carrageenan-induced paw oedema models in rats produced statistically significant reductions in swelling. 2 The primary active constituents include anthraquinones purpurin, alizarin, rubiadin and munjistin, which modulate inflammatory pathways including NF-κB signalling. 1 A 2022 study further demonstrated that R. cordifolia ameliorates ulcerative colitis in mice through dual inhibition of the NLRP3 inflammasome and IL-6/JAK2/STAT3 pathways. 5
Rubiadin — a dihydroxyanthraquinone isolated from R. cordifolia — was shown to dose-dependently restore elevated liver enzymes (SGOT, SGPT, SALP, γ-GT) towards normal values in CCl₄-induced hepatic damage in rats, and prevent glutathione depletion in the liver. Results were comparable to silymarin, a well-established liver-protective reference drug. 6
Tripathi et al. established that rubiadin inhibits FeSO₄-induced lipid peroxidation in rat liver in a dose-dependent manner. 7 Root extracts of R. cordifolia have been found to contain high levels of total phenolics (up to 392.9 mg GAE/g in the methanol fraction), contributing to strong DPPH radical-scavenging activity. 8
Phytoconstituents of R. cordifolia have demonstrated antifungal and antibacterial activity against gram-positive organisms (Bacillus subtilis, Staphylococcus aureus) and gram-negative pathogens including Pseudomonas aeruginosa. In one study it was significantly more active against B. subtilis and S. aureus than streptomycin and penicillin G used as standards. 24
R. cordifolia extracts can inhibit melanin synthesis, offering a scientific basis for its traditional use in reducing hyperpigmentation. 4 In one clinical observation of eczema patients, topical application of a Manjistha ointment produced a 50% reduction in severity score within four days, with significant relief of oedema, exudation, and itching. 2
The alcoholic extract of R. cordifolia restores immune parameters compromised by ethanol toxicity in animal models — including improvements in humoral and cell-mediated immune response, phagocytosis, total leukocyte count, and antioxidant enzyme activities (SOD, CAT, GSH). 10 These findings align with its classical description as an immune regulator (rasayana).
A 2023 study published in Pharmaceuticals (Basel) found that R. cordifolia attenuated diabetic neuropathy in rats by inhibiting apoptosis and reducing oxidative stress, suggesting emerging potential in neurological conditions associated with metabolic disease. 11
Traditional Use & Modern Dosage
| Form | Traditional Preparation | Typical Dose (Adult) |
|---|---|---|
| Powder (Churna) | Ground dried root, mixed with warm water, honey or ghee | 1–6 g/day in divided doses |
| Decoction (Kwath) | 1 tbsp root boiled in 2 cups water until halved; strained | 20–50 ml twice daily |
| Capsules / Tablets | Standardised extract or powder in modern encapsulation | 500–1,000 mg twice daily |
| Tincture | 1:2 hydro-alcoholic extract (25% ethanol) | 3–12 ml/day in divided doses |
| Topical Oil (Taila) | Root infused in sesame or coconut oil; massage into affected area | Apply 1–3× daily to affected skin |
Traditionally, Manjistha is taken for 4–8 weeks in a therapeutic cycle followed by a rest period — especially in detox or skin-clearing programmes.
Safety & Precautions
Please note
- Excessive intake may cause mild constipation due to astringent, drying nature
- High doses may produce harmless reddish discolouration of urine or stool (natural anthraquinone pigments)
- Pregnancy & breastfeeding: use only under professional guidance 1
- Mild anti-platelet activity — consult a healthcare provider before concurrent use with anticoagulants
