Saffron for Conjunctivitis

Saffron has a narrow therapeutic window, and the biggest safety risk is one most people never consider: adulteration. Setting that aside, at classical doses (30-100 mg daily) in healthy adults, saffron is extremely well-tolerated, the clinical trials supporting its use report side-effect profiles comparable to placebo. But there are several situations where caution is essential.

Adulteration: The Real Safety Issue

Saffron is the single most adulterated spice on the planet. Industry studies estimate 40-90% of saffron sold outside dedicated spice markets is either diluted or entirely fake. Common substitutes: dyed safflower petals, turmeric, dyed corn silk, coconut fibres, marigold petals, and synthetic dyes like tartrazine and Sudan red (carcinogenic azo dyes banned in food).

Buy whole threads, not powder. Choose certified Kashmiri Mongra, Iranian Sargol, or Spanish La Mancha. If the price is dramatically below market (~$5-20 per gram), it is almost certainly adulterated. Do the warm water test (see How to Use).

Toxicity & Overdose

This is one of the few Ayurvedic herbs where dose genuinely matters. Doses above 1.5 g per day can cause vomiting, uterine bleeding, bloody diarrhea, yellowing of the skin, dizziness, and numbness. The lethal dose is approximately 5 g, only about 30 times a normal therapeutic dose, well within reach if someone wrongly assumes "more is better." Never exceed 1 g per day without practitioner supervision.

Pregnancy, Contraindicated at Therapeutic Doses

Saffron is a uterine stimulant, classical texts explicitly describe it as a uterine tonic that promotes menstrual flow, and it has been used historically as an abortifacient at high doses. Therapeutic doses (30+ mg/day) and extracts are contraindicated during pregnancy. The traditional practice of giving pregnant women a thread or two in milk for the baby's complexion is folk tradition, not medicine; if you choose to follow it, stay at 1-2 threads and discuss with your obstetrician. There is no clinical safety data to support therapeutic saffron use in pregnancy.

Drug Interactions

• Antidepressants (SSRIs, MAOIs, tricyclics): Saffron has serotonergic activity. Combination raises a theoretical risk of serotonin syndrome. Don't stack with prescription antidepressants without practitioner oversight.
• Antihypertensives: Saffron can lower blood pressure. Monitor if you're on BP medication, risk of hypotension.
• Anti-diabetic drugs: May enhance glucose-lowering effect. Monitor blood sugar.
• Anticoagulants (warfarin, aspirin, clopidogrel): Saffron has mild antiplatelet activity. Caution if you're on blood thinners or have bleeding disorders.

When to Use Caution

• Bleeding disorders: Avoid therapeutic doses.
• Bipolar disorder: Anecdotal reports of mood elevation; use only under psychiatric supervision.
• Scheduled surgery: Stop saffron at least 2 weeks before due to antiplatelet effect.
• High-Pitta heat conditions with active inflammation: Although generally cooling, saffron's potency is classically described as warming by Bhavaprakash. Combine with cooling anupanas (milk, ghee) or reduce dose.

Side Effects at Normal Doses

At 30-100 mg/day, reported side effects are uncommon and mild: occasional nausea, headache, decreased appetite, or dry mouth. These resolve on dose reduction or discontinuation.
