## Overview

Adhatoda vasica is an Ayurvedic herb containing vasicine and vasicinone alkaloids that support respiratory health through bronchodilatory and [anti-inflammatory](/ingredients/condition/inflammation) mechanisms. Clinical evidence shows it reduces inflammatory markers IL-6 and TGF-β1 while supporting recovery in mild respiratory conditions.

## Health Benefits

• Respiratory support in mild COVID-19: Clinical trial (n=136) showed reduced inflammatory markers and 100% recovery without progression to severe disease (PMID: 38049897)
• [Anti-inflammatory](/ingredients/condition/inflammation) effects: Reduces IL-6, TGF-β1, and inflammation-related gene expression based on preclinical and clinical evidence
• Hypoxia protection: Downregulates HIF-1α and improves survival in hypoxia models, with clinical reduction of hypoxia markers
• [Digestive health](/ingredients/condition/gut-health): Open-label trial showed reduction in gastric acid levels for non-ulcer dyspepsia (PMID: 22557371)
• [Antiviral](/ingredients/condition/immune-support) activity: Demonstrated inhibition of SARS-CoV-2 replication in Vero cells and faster viral clearance in combination therapy

## Mechanism of Action

Adhatoda vasica's primary bioactive compounds vasicine and vasicinone act as bronchodilators by relaxing smooth muscle in airways. The herb reduces [pro-inflammatory cytokine](/ingredients/condition/inflammation)s IL-6 and TGF-β1 while modulating inflammation-related gene expression. Vasicine also demonstrates expectorant properties by increasing respiratory secretions and improving mucus clearance.

## Clinical Summary

A randomized controlled trial (n=136) in mild COVID-19 patients showed Adhatoda vasica significantly reduced inflammatory markers IL-6 and TGF-β1, with 100% recovery rates and no progression to severe disease. The study demonstrated measurable [anti-inflammatory](/ingredients/condition/inflammation) effects with reduced inflammation-related gene expression. However, clinical evidence remains limited to this single trial, requiring additional research to establish broader therapeutic applications and optimal dosing protocols.

## Nutritional Profile

Adhatoda vasica (Malabar nut) is a medicinal shrub rather than a dietary food source; its nutritional profile centers on bioactive phytochemicals rather than conventional macronutrients. Key bioactive compounds include: Alkaloids (primary class) — Vasicine (peganine) at approximately 0.541–1.0% dry weight of leaves (the dominant alkaloid and principal active constituent), Vasicinone at ~0.07–0.15% dry weight, Vasicol, Adhatodine, Adhavasine, and Vasicinol present in trace quantities (<0.05%); Flavonoids — Quercetin, Kaempferol, Apigenin, and Vitexin detected in leaf extracts (total flavonoid content reported at approximately 12–18 mg quercetin equivalents per gram dry extract); Tannins — approximately 2–5% by dry weight; Phenolic acids — Gallic acid, caffeic acid, and ferulic acid present in measurable quantities (total phenolics ~25–40 mg gallic acid equivalents per gram dry extract); Saponins — approximately 1–3% dry weight; Essential oils — trace volatile compounds including terpinene and linalool; Sterols — β-sitosterol and stigmasterol identified chromatographically. Macronutrient data for raw leaf (limited data): crude protein ~12–15% dry weight, crude fiber ~18–22% dry weight, ash content ~8–10% dry weight. Micronutrients detected include calcium (~1,200–1,800 mg/100g dry leaf), iron (~15–25 mg/100g dry leaf), potassium (~900–1,200 mg/100g dry leaf), and zinc (~2–4 mg/100g dry leaf). Bioavailability notes: Vasicine is moderately bioavailable orally; alkaloid absorption is enhanced in aqueous decoctions compared to raw powder; co-administration with piperine has been shown in preclinical models to improve extraction efficiency. The plant is not consumed as food; therapeutic doses are derived from standardized extracts or traditional decoctions, not nutritional intake.

## Dosage & Preparation

Clinically studied doses include 500mg oral Adhatoda vasica herbal extract (Vasa Ghan) daily for 14 days for COVID-19 support. For digestive issues, AV syrup has been used (specific dosage not reported in trials). No standardization details regarding vasicine content were provided in human studies. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Adhatoda vasica is generally well-tolerated in clinical studies with no serious adverse events reported. The herb may interact with bronchodilator medications due to its similar mechanisms, potentially enhancing effects. Pregnant and breastfeeding women should avoid use as vasicine alkaloids may have uterine stimulant properties. Individuals with hypotension should use caution as the herb may further lower [blood pressure](/ingredients/condition/heart-health).

## Scientific Research

A randomized open-label trial (n=136 completed) tested 500mg/day AV extract for 14 days in mild COVID-19 patients, showing reduced inflammatory markers and no disease progression (PMID: 38049897). An open-label trial demonstrated efficacy in reducing gastric acid in non-ulcer dyspepsia (PMID: 22557371). Most other evidence comes from preclinical models showing [anti-inflammatory](/ingredients/condition/inflammation) and anti-hypoxic mechanisms.

## Historical & Cultural Context

Adhatoda vasica has been used in Ayurveda as 'Vasa' for centuries, primarily for respiratory conditions like Tamaka Shwasa (asthma), cough, and hyperacidity (Amlapitta). Traditional formulations include Vasa Ghana, Vasa Ghrita, and Vasa Avaleha, which showed efficacy in asthma symptom relief according to clinical reviews.

## Frequently Asked Questions

### What is the active compound in Adhatoda vasica?

The primary active compounds are vasicine and vasicinone, quinazoline alkaloids responsible for the herb's bronchodilatory and anti-inflammatory effects. Vasicine concentrations typically range from 0.5-2% in quality extracts.

### How much Adhatoda vasica should I take daily?

Clinical studies used standardized extracts providing specific alkaloid concentrations, but optimal dosing isn't established. Traditional Ayurvedic preparations typically use 3-6 grams of dried leaf powder daily, though standardized extracts may require different amounts.

### Can Adhatoda vasica help with asthma symptoms?

Preclinical studies suggest vasicine's bronchodilatory properties may support airway function, but clinical trials specifically for asthma are lacking. The anti-inflammatory effects on IL-6 and TGF-β1 may theoretically benefit respiratory conditions, but medical supervision is essential.

### Is Adhatoda vasica safe with blood pressure medications?

Adhatoda vasica may lower blood pressure through vasodilation, potentially enhancing antihypertensive medications. This could lead to excessive blood pressure reduction, requiring medical monitoring and possible medication adjustments when used concurrently.

### How long does it take for Adhatoda vasica to work?

In the clinical trial for respiratory support, measurable reductions in inflammatory markers IL-6 and TGF-β1 occurred within the treatment period, though exact timeframes weren't specified. Traditional use suggests benefits may be noticed within days to weeks of consistent use.

### What does clinical research show about Adhatoda vasica for respiratory health?

A clinical trial with 136 participants demonstrated that Adhatoda vasica reduced inflammatory markers and achieved 100% recovery without progression to severe disease in mild respiratory conditions. The herb downregulates key inflammatory cytokines including IL-6 and TGF-β1, supporting its traditional use for respiratory support. Preclinical evidence also shows it protects against hypoxia by modulating HIF-1α pathways, suggesting potential benefits during respiratory compromise.

### Who benefits most from Adhatoda vasica supplementation?

Adhatoda vasica is traditionally used and clinically studied for individuals experiencing mild respiratory symptoms, chronic cough, and inflammatory airway conditions. Those seeking natural anti-inflammatory support for respiratory health may benefit from this herb, particularly when combined with conventional respiratory management. People with mild hypoxia-related concerns or elevated inflammatory markers may also be candidates, though consultation with a healthcare provider is recommended.

### How does Adhatoda vasica compare to other traditional respiratory herbs?

Adhatoda vasica is distinguished by its clinical evidence for reducing inflammatory cytokines and preventing progression to severe respiratory disease, supported by trial data from 136 participants. Unlike many traditional respiratory herbs, it has been studied for both anti-inflammatory effects and hypoxia protection through HIF-1α modulation. Its efficacy appears comparable to other Ayurvedic respiratory herbs, though it offers unique data in mild respiratory conditions with inflammatory components.
