💊 Marigold in the medicine industry
Marigold (calendula's cousin) petals are used in skin ointments and eye washes; marigold extracts are used in cosmetics and traditional medicine for wound healing and inflammation.
🌱 Growing & care tips
Marigolds need full sun and ordinary soil; they bloom all season if you deadhead the spent flowers, and they are famously easy from seed.
🍽️ How to use it
The petals are edible and add colour to salads; marigold (calendula) ointments soothe skin; the flowers are used as natural food colouring in cheese and butter.
💡 Did you know? Marigolds are nature's pest repellent — gardeners plant them near tomatoes to deter whiteflies, and their roots release chemicals that suppress soil nematodes.
⚠️ Marigold safety note: Most marigolds are safe, but people allergic to daisies, ragweed or chrysanthemums may react to marigold flowers; calendula ointment is for skin use.
⚠️ 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.
