What is Lohasava?
Lohasava (लोहासव) is a classical Ayurvedic fermented liquid formulation (Asava) prepared using iron (Loha) as its primary therapeutic ingredient, combined with a complex blend of herbs and natural fermentation agents. Asavas are self-generated alcohol preparations in which the sugar and starch-containing ingredients undergo natural fermentation, producing an endogenous low-level alcohol content (approximately 5–10%) that serves as a bioavailability enhancer and preservative, carrying the therapeutic principles of the herbs into deep tissues. Lohasava is described in the Bhaishajya Ratnavali and is one of the classical formulations for Pandu (anaemia), Arshas (haemorrhoids), Grahani (malabsorption), and Krimi Roga (parasitic and infective intestinal conditions). It combines the haematopoietic properties of iron with the digestive and hepatoprotective action of multiple herbs in a highly bioavailable liquid form.

Ingredients of Lohasava
- Loha Churna (iron filings/powder, Ferrum) – primary haematopoietic ingredient
- Triphala (Haritaki, Vibhitaki, Amalaki) – detoxifying base, iron absorption enhancer
- Vidanga (Embelia ribes) – anthelmintic, Krimi Nashaka
- Musta (Cyperus rotundus) – digestive, anti-inflammatory
- Dhataki Pushpa (fire-flame bush, Woodfordia fruticosa) – natural fermentation initiator
- Madhuka Pushpa (mahua flower, Madhuca longifolia) – fermentation sugar source
- Haridra (turmeric, Curcuma longa) – anti-inflammatory, antimicrobial
- Chitraka (Plumbago zeylanica) – digestive stimulant, Deepana
- Honey and Jaggery – fermentation substrates and mild sweeteners
Health Benefits of Lohasava
1. Anaemia (Pandu Roga) — Primary Indication
Lohasava is one of the most frequently prescribed classical formulations for Pandu Roga (iron-deficiency anaemia). The fermented liquid format dramatically improves the bioavailability of iron compared to crude iron preparations — the self-generated alcohol content facilitates iron absorption through intestinal mucosa, while Amalaki (Vitamin C-rich) further enhances ferrous iron uptake. Clinical presentation of Pandu — pallor of skin and mucous membranes, breathlessness, weakness, and palpitations — is directly addressed by the haematopoietic action of Lohasava.
2. Haemorrhoids (Arshas)
Lohasava is a classical first-line formulation for Arshas (haemorrhoids), particularly bleeding and prolapsed haemorrhoids with an Ama-Kapha aetiology. Its astringent and haemostatic properties reduce venous engorgement and bleeding, while the digestive herbs (Musta, Chitraka, Vidanga) address the underlying constipation and Mandagni (digestive weakness) that aggravate haemorrhoidal disease. The mild laxative effect of the fermented preparation supports regular elimination without straining.
3. Malabsorption and Sprue (Grahani Roga)
Grahani, the Ayurvedic correlate of malabsorption syndrome, involves impaired function of the small intestine (Grahani — the intestinal holding and processing organ). Lohasava’s Deepana-Pachana action rekindled by Chitraka and Musta, combined with the Tikshna property of the iron and fermented base, restores Grahani function, improves nutrient absorption, and addresses the alternating constipation-diarrhoea pattern characteristic of this condition.
4. Intestinal Parasites (Krimi Roga)
Vidanga (Embelia ribes), one of Ayurveda’s foremost Krimighna (antiparasitic) herbs, is a key ingredient in Lohasava. It creates an inhospitable environment for intestinal worms and protozoan parasites, while the Tikshna and Ushna properties of the fermented formulation further support parasite elimination. Lohasava is specifically indicated in Udararoga (abdominal disorders) with Krimi involvement — including worm infestations presenting with anaemia, abdominal pain, and poor growth in children.
5. Liver and Spleen Disorders
The combination of iron, Triphala, and hepatoprotective herbs in Lohasava addresses both Yakrit (liver) and Pliha (spleen) disorders — classical correlates of hepatosplenomegaly, cirrhosis, and portal hypertension presentations. The Triphala base supports hepatic detoxification and bile production, while iron rebuilds Rakta Dhatu quality impaired by hepatic dysfunction. Classical texts indicate Lohasava specifically in Yakriddalyudara (hepatomegaly with ascites).
6. Skin Disorders with Blood Impurity
Lohasava’s Rakta-shodhaka (blood-purifying) properties, driven by Triphala, Haridra, and the iron-mediated Rakta Dhatu rebuilding action, support management of chronic skin diseases (Kustha) with an anaemia or Ama-Rakta component. It is particularly useful when skin disorders coexist with digestive weakness and anaemia — a combination where purely topical or single-system treatments are insufficient.
7. Post-Partum Recovery and Nutritional Replenishment
Blood loss during delivery can cause significant Pandu and Dhatukshaya (tissue depletion) in new mothers. Lohasava’s highly bioavailable iron combined with digestive herbs supports rapid Rakta Dhatu regeneration in the post-partum period. Its Asava format is well-tolerated, easy to administer, and avoids the gastrointestinal discomfort of conventional iron supplements, making it suitable for nursing mothers under physician guidance.
How to Use Lohasava
| Form | Dosage | How to Take |
|---|---|---|
| Lohasava liquid | 15–30 mL | Twice daily after meals, mixed with equal quantity of warm water |
| With warm water (standard) | 15–20 mL | Twice daily post-meals; standard administration for anaemia and haemorrhoids |
| Children (8–12 years) | 5–10 mL | Twice daily with equal warm water; for anaemia with intestinal parasites |
| As prescribed | Physician-directed | Duration typically 4–12 weeks; review by physician after each course |
Side Effects & Precautions
Lohasava is generally safe at recommended doses. The self-generated alcohol content (~5–10%) means it should not be given to individuals with alcohol sensitivity, liver cirrhosis, or those observing strict alcohol abstinence — consult a physician for alternative formulations. Its Ushna (hot) property may cause loose stools or gastric discomfort in Pitta-dominant individuals; if this occurs, reduce the dose or dilute with more water. Haemochromatosis (iron overload) is a contraindication. Pregnant women should use it only under physician supervision. Do not use in children under 5 years without specific paediatric Ayurvedic guidance.
Classical References
Lohasava is described in the Bhaishajya Ratnavali (Pandurogandhikara and Arshognadhikara) and the Sharangdhara Samhita (Asava-Arishta chapter). It is classified under Pandu Nashaka, Arshohara, Grahani-nashaka, and Krimighna formulations in classical Ayurvedic literature. The formulation is included in the Ayurvedic Formulary of India as a standardised fermented iron tonic.
