💊 Spinach in the medicine industry
Spinach is packed with iron, folate and vitamin K; its lutein and zeaxanthin support eye health, and it is a staple of iron-rich diets and supplements.
🌱 Growing & care tips
Spinach grows fast in cool weather and part sun; sow every few weeks for a continuous crop and pick outer leaves first. It bolts (runs to seed) in summer heat.
🍽️ How to use it
Spinach is eaten raw in salads, wilted into eggs and curries, blended into smoothies and soups; baby leaves are the most tender.
💡 Did you know? Spinach's famous iron was the result of a decimal error — an 1870s researcher misplaced a decimal point, making the iron content look ten times higher than it is.
⚠️ Spinach safety note: Spinach is rich in vitamin K, which helps blood clot — people on warfarin (a blood thinner) should keep their spinach intake consistent and tell their doctor.
⚠️ Important: Herbal and plant remedies can interact with medicines. Always ask a doctor or pharmacist before using any plant product for health purposes — especially if you are pregnant, breastfeeding or taking prescription drugs.
