Sahjan (सहजन), commonly called the Drumstick Tree or Moringa, botanically Moringa oleifera Lam., Moringaceae family, is a fast-growing deciduous tree native to the sub-Himalayan regions of Northwest India and now cultivated across tropical Africa, Asia, and Latin America. Ayurveda classifies it as a premier Shigru herb with tridoshic balancing properties, addressing over 300 conditions in classical literature. Modern nutrition science validates Moringa as one of the most nutrient-dense plants on Earth — with leaves containing 7× the vitamin C of oranges, 4× the calcium of milk, and 2× the protein of yogurt.

Health Benefits of Sahjan (Moringa)
1. Exceptional Nutritional and Anti-anaemia Properties
Moringa leaves are among the most nutrient-dense foods studied — containing complete protein (all 9 essential amino acids), iron (25 mg per 100 g dry weight), calcium, vitamins A, C, E, and K, and B-vitamins. In Ayurveda this corresponds to Rasayana action — the ability to replenish all seven dhatus (bodily tissues). Supplementation with Moringa leaf powder (3–5 g/day) significantly raised haemoglobin levels in anaemic adolescent girls in multiple clinical trials.
2. Anti-inflammatory and Arthritis Relief
Moringa’s isothiocyanates (particularly moringin and moringinin) are potent NF-κB inhibitors that reduce systemic inflammation at the molecular level. A 2015 randomised controlled trial showed Moringa leaf extract reduced CRP and TNF-α significantly. Classically it is used in Amavata (rheumatoid arthritis), Gout (Vatarakta), and musculoskeletal pain, often as a decoction or leaf powder with warm water.
3. Blood Sugar Regulation
Moringa is one of the best-studied anti-diabetic plants. Chlorogenic acid in the leaves inhibits intestinal glucose absorption and improves insulin receptor sensitivity. A 2014 meta-analysis confirmed significant fasting blood glucose reduction with Moringa supplementation. In Ayurveda it is classified under Pramehaghna herbs for managing Prameha (urinary metabolic disorders including diabetes).
4. Liver Protection and Detoxification
Moringa seeds contain oleic acid and quercetin that significantly reduce hepatic lipid accumulation, oxidative stress, and liver enzyme elevation (AST, ALT). In Ayurveda, Shigru is a Yakrituttejaka (liver stimulant) used for fatty liver, Kamala (jaundice), and toxin clearance. The seed oil is also used topically for skin detoxification.
5. Antimicrobial and Antiparasitic Action
Moringa seeds contain the natural flocculant dimethyl octadecylamine that precipitates bacteria and sediment from water — earning it use in water purification. Its isothiocyanates and pterygospermin inhibit both gram-positive and gram-negative bacteria. Classical Ayurveda classifies it as Krimighna for intestinal worms and Vranaropana for infected wounds.
6. Thyroid and Hormonal Support
Emerging research suggests Moringa leaf extract modulates thyroid hormone levels, potentially supporting those with hypothyroidism by stimulating T3 and T4 production. However, those already on thyroid medications should exercise caution and consult their physician, as the interaction is bidirectional depending on dose. Ayurvedic texts note its role in Galaganda (goitre-like thyroid conditions).
7. Cardiovascular and Cholesterol Benefits
Moringa’s beta-sitosterol and quercetin reduce LDL cholesterol, inhibit platelet aggregation, and lower blood pressure via ACE-inhibitory peptides in the seeds. Human trials confirm reductions of 6–15% in LDL with regular Moringa supplementation. Classically, Shigru is listed as Hridya (cardiac tonic) and used in formulations for heart health.

Side Effects and Precautions
Known Contraindications
- Root bark contains the alkaloid spirochin which can cause nerve damage — root bark should never be consumed internally.
- High doses of leaf powder may cause digestive upset, diarrhoea, or lower blood pressure excessively.
Drug Interactions
- May potentiate antidiabetic drugs — monitor blood glucose closely.
- May interact with thyroid medications (levothyroxine) — space consumption by at least 4 hours.
- Possible additive effect with antihypertensives — monitor blood pressure.
Who Should Avoid
- Pregnant women — root bark is abortifacient; seed preparations should be used cautiously.
- Breastfeeding mothers should limit to culinary amounts (leaves are traditionally used as galactagogue but concentrated extracts need caution).
Safe Dosage Range
Leaf powder: 3–5 g per day (up to 10 g under supervision). Fresh leaves and pods in culinary quantities: unrestricted. Seeds: 2–3 seeds per day for water purification/internal use. Root bark: contraindicated internally. Always prefer leaves and pods for regular use.
Classical Text References
Charaka Samhita (Sutrasthana 27) lists Shigru (Moringa) among the Katu skandha herbs with deepana, shothahara, and krimighna properties. Ashtanga Hridayam (Sutrasthana 6.108) recommends Shigru for Amavata, Kushtha, and Shotha. The Bhavaprakash Nighantu (Shigru varga) dedicates a full chapter to Moringa, noting over 40 therapeutic indications for its bark, root, leaf, flower, pod, and seed.
