• Anti-diabetic
• Antimicrobial
• Hepatoprotective

How does it work?

• Moringa isothiocyanate-1 (MIC-1) activates Nrf2 pathway by releasing Nrf2 from Keap-1 complex, increasing nuclear translocation and expression of antioxidant enzyme genes (NQO1, HO-1, GCLC).
• MIC-1 suppresses NF-kB pathway by preventing phosphorylation of IkB and nuclear translocation of NF-kB, reducing transcription of pro-inflammatory genes.
• Dual NF-kB suppression and Nrf2 activation provides simultaneous anti-inflammatory and antioxidant effects.
• MIC-1 upregulates glutathione S-transferases (GST), preventing cell damage through reduced glutathione reactions with xenobiotics and ROS.
• Suppresses pro-inflammatory cytokines in LPS-stimulated macrophages.
• Reduces reactive oxygen species in high-glucose-treated human renal proximal tubule cells (HK-2), relevant to diabetic nephropathy.
• Transcriptomic analysis shows MIC-1 modulates inflammation, immunity, and oxidative stress pathways simultaneously.
• Rich in isothiocyanates, flavonoids, phenolic acids, and glucosinolates that act as indirect antioxidants.

How is it used traditionally?

Called ‘Shigru’ in Ayurveda. Used extensively in Dashamoola preparations. Indicated for Shotha (inflammation), Krimi (parasites), and Vata disorders.

Where is it described in the classical texts?

• Charaka Samhita
• Bhavaprakasha Nighantu (Guduchyadi Varga)

Recent safety updates

• Avoid consumption of root and root extracts - these parts contain potentially toxic compounds.
• Safety and efficacy in pregnancy and lactation is not established - information lacking.
• May inhibit conversion of thyroxine (T4) to triiodothyronine (T3) in animal studies - potential interaction with levothyroxine.
• May decrease how quickly the liver breaks down some medications (CYP enzyme inhibition), potentially increasing drug effects and side effects.
• May lower blood sugar - caution with diabetes medications to avoid hypoglycemia.
• May lower blood pressure - potential additive effect with antihypertensive drugs.
• Generally well tolerated at doses up to 4 g with no significant increase in adverse events in clinical studies.
• Transient diarrhea is the most common side effect.
• Rare case reports: Stevens-Johnson syndrome reported, and cutaneous toxicity with respiratory distress and tongue edema following moringa powder consumption.

Recommended Dosage

Leaf powder: 2-6g/day; Fresh leaves: 10-20g/day

Safety, contraindications and cautions

• Pregnancy (root bark — abortifacient)
• Thyroid conditions (goitrogenic at high doses)
• May lower blood pressure

What is it made of?

Part(s) Analyzed: Leaf, Fruit (pod), Seed, Bark, Root, Flower

Key Active Markers

• Isothiocyanates
• Quercetin
• Chlorogenic acid
• Beta-carotene
• Vitamin C
• Iron

Analytical Methods: HPLC fingerprinting, TLC (identity), LC-MS/MS (marker quantification)

Dosage forms and preparation

Dosage Forms: Churna (leaf powder), Capsules, Tablets, Leaf extract, Seed extract, Oil (Ben oil/Moringa oil), Tea/Infusion, Drumstick pod preparations, Protein powder

Standard Dosage: 3-6 g leaf powder per day; 500-1500 mg standardized leaf extract daily; 5-10 mL Moringa oil for culinary/topical use; 1-2 g seed powder for water purification

Bioavailability: Isothiocyanates (from glucosinolates) are well absorbed (~70-80%). Quercetin glycosides undergo intestinal hydrolysis with moderate aglycone absorption (~25%). Beta-carotene bioavailability is fat-dependent - co-administer with lipids. Iron and calcium in Moringa leaves show 20-30% absorption rate. Moringa oleifera coagulant protein shows local GI activity without significant systemic absorption.

Optimal Timing: Morning with breakfast for nutritional supplementation; before meals for glycemic management; leaf tea between meals; Moringa oil topically at night for skin health

Standardized Extract: Shade-dried leaf powder standardized to minimum 1% isothiocyanates, 5% protein, and 0.5% total flavonoids. Leaf extract (10:1 hydroalcoholic) standardized to minimum 3% quercetin equivalents. Cold-pressed seed oil (Ben oil) meeting cosmetic grade standards. Seed protein isolate for water purification applications.

Shelf Life: Dried leaf powder: 18-24 months. Capsules/tablets: 24 months. Ben oil: 36+ months (exceptional oxidative stability). Tea bags: 18 months. Fresh leaves: 3-5 days refrigerated.

Storage: Leaf powder in airtight, light-resistant containers below 25 deg C (beta-carotene and chlorophyll are photosensitive). Ben oil at room temperature in dark glass bottles. Capsules in blister packs. Fresh leaves at 4-8 deg C. Protect all forms from humidity.
