Adhatoda (Justicia adhatoda) is a traditional respiratory herb containing vasicine and vasicinone alkaloids that act as bronchodilators and expectorants. The plant works by relaxing bronchial smooth muscle and reducing airway inflammation through phosphodiesterase inhibition.
Origin & History
Justicia adhatoda, commonly known as Adhatoda or Malabar nut, is a perennial shrub native to South Asia, particularly India and Thailand. The plant's leaves, roots, and flowers are harvested and processed into various forms including fresh extracts, dried powders, decoctions, juices, essential oils, and syrups.
Research Narrative (Provisional)
A 2015 Indian Chest Society clinical trial confirmed that leaf extract reduced cough frequency, sputum viscosity, and breathlessness in chronic bronchitis patients. A double-blind placebo-controlled study demonstrated vasicine-rich extract improved FEV1 values by 15% over 4 weeks in mild-to-moderate asthmatic patients. Note: The research dossier does not provide complete PubMed identifiers for these studies.

Nutritional Profile
Adathoda (Justicia adhatoda) is a medicinal herb primarily valued for its bioactive alkaloid content rather than conventional macronutrient density. Key bioactive compounds include: Vasicine (peganine) as the principal alkaloid at approximately 0.541-1.0% dry weight in leaves, responsible for bronchodilatory and expectorant activity; Vasicinone, an oxidation product of vasicine present at ~0.05-0.08% dry weight, contributing to bronchodilation; Vasicinol and deoxyvasicine present in smaller trace quantities (<0.05% dry weight). Leaves also contain quinazoline alkaloids collectively estimated at 1.5-2.0% total alkaloid content by dry weight. Flavonoids present include kaempferol, astragalin, and quercetin derivatives at approximately 0.3-0.8% dry weight. Phenolic compounds including apigenin and luteolin glucosides contribute antioxidant activity. Essential oils account for roughly 0.1-0.3% of leaf weight. Crude protein content in dried leaves is approximately 15-18% dry weight, with crude fiber around 12-15% dry weight. Mineral content includes moderate potassium (~1,200 mg/100g dry leaf), calcium (~800 mg/100g dry leaf), and iron (~25 mg/100g dry leaf). Vitamin C is present at approximately 40-60 mg/100g fresh leaf weight. Bioavailability note: Vasicine exhibits good oral bioavailability in animal models with rapid gastrointestinal absorption; however, human pharmacokinetic data remains limited. Tannins present (~4-6% dry weight) may moderately reduce mineral bioavailability through chelation.
Reported Mechanism (Provisional)
Adhatoda's primary bioactive compounds vasicine and vasicinone inhibit phosphodiesterase enzymes, leading to increased cAMP levels and bronchial smooth muscle relaxation. These alkaloids also exhibit anti-inflammatory effects by modulating histamine release from mast cells and reducing pro-inflammatory cytokine production. The expectorant action occurs through stimulation of respiratory tract secretions via cholinergic pathways.
Clinical Narrative (Provisional)
A randomized controlled trial in chronic bronchitis patients showed significant reduction in cough frequency and breathlessness within 7-14 days of treatment. A double-blind placebo-controlled study of asthma patients demonstrated a 15% improvement in FEV1 values over 4 weeks of supplementation. The antimicrobial properties have been validated in vitro against respiratory pathogens. Evidence quality is moderate due to limited sample sizes and need for larger multicenter trials.
