Ayurvedic management of pulmonary tuberculosis: A systematic review.

The short version

This systematic review pooled published research on using Ayurveda, India's traditional medical system, alongside standard drugs for pulmonary tuberculosis (PTB) — a bacterial lung infection that remains one of India's leading causes of death. The review searched PubMed through April 2015 and found six studies worth including: four human trials testing Ayurvedic herbal formulas as add-ons to standard anti-TB drugs (ATDs), and two lab studies testing plant extracts directly against the TB bacterium. In Ayurveda, PTB is traditionally understood as Rajayakshma, a wasting condition tied to depleted bodily tissues (dhatu) and vital reserve (ojas) — explaining why many of the formulas studied are rejuvenative "Rasayana" tonics rather than antibiotics. The four clinical trials enrolled 30 to 133 PTB patients each, all in India, and ran from 28 days to 6-8 months. Participants took Ayurvedic formulas — a nine-herb Rasayana capsule, a liquid tonic called Bhringarajasava, Ashwagandha with Chyawanprash, or a hepatoprotective blend called Liv-600 — alongside their prescribed drug regimen (DOTS). Researchers tracked symptoms like cough and fever, body weight, X-ray changes, drug blood levels, and liver enzymes. The two lab studies tested leaf and plant extracts against TB bacteria in culture, measuring the lowest concentration that stopped bacterial growth. Across the trials, Ayurvedic add-ons consistently eased symptoms and supported weight gain more than standard treatment alone (p<0.001 in the largest trial). One striking finding: Ashwagandha plus Chyawanprash raised blood levels of two key TB drugs, isoniazid and pyrazinamide, by 7-10% (meaning the body absorbed more of the medicine that actually kills the bacteria) — potentially valuable given rising drug resistance. The hepatoprotective blend showed no harmful rise in liver enzymes, suggesting it may guard against the liver damage these drugs can cause. In the lab, extracts from four of five tested legumes completely stopped bacterial growth at a low concentration (50 micrograms per milliliter), and extracts from five other plants inhibited even drug-resistant TB strains by up to 95%. These findings position Ayurvedic formulas as promising supportive care — easing symptoms, protecting the liver, and possibly boosting drug absorption — rather than replacements for standard TB treatment, which no study tested. The evidence base is thin: only six studies total, all small, mostly from India, with just one describing blinding and none pooling results statistically. The authors call for properly designed clinical trials of the lab-active plants, especially against multidrug-resistant TB. The evidence reviewed concerns Ayurvedic preparations as adjuncts to prescribed drug therapy; none of it addresses their use instead of it.

Key findings

• A systematic review of six studies found that traditional Ayurvedic herbal formulas, when taken alongside standard anti-TB drugs (ATDs), consistently reduced tuberculosis symptoms such as cough, fever, and breathlessness compared to standard treatment alone.
• One trial found that combining Ashwagandha (an adaptogenic Ayurvedic herb) with Chyawanprash (a polyherbal tonic) increased blood levels of the TB drugs isoniazid and pyrazinamide by 7-10%, meaning patients' bodies absorbed more of the medicine that fights the infection.
• A hepatoprotective (liver-protecting) Ayurvedic blend called Liv-600 and a Bhumyamalaki (Phyllanthus fraternus) herbal decoction showed no harmful rise in liver enzymes, suggesting they may help guard against the liver damage anti-TB drugs can cause.
• In laboratory testing, extracts of several plants — including four types of legume leaves and five other medicinal plants — stopped or slowed the growth of Mycobacterium tuberculosis, the bacterium that causes TB, including strains resistant to multiple drugs (MDR-TB).
• The evidence remains preliminary: all six included studies were small (30-133 participants, or lab-only), came mostly from a single country, and none used a full randomized controlled trial design; the studies examined these Ayurvedic approaches as adjuncts to standard prescribed TB treatment, not as replacements.
