💊 Olive Tree in the medicine industry
Olive oil is the heart of the Mediterranean diet, rich in monounsaturated fats and polyphenols studied for heart health; olive leaf extract is used in supplements for blood pressure support.
🌱 Growing & care tips
Olive trees need full sun, excellent drainage and little water once established; they live for centuries and fruit best in hot, dry summers.
🍽️ How to use it
Olives are cured and eaten whole, pressed into olive oil, and used in salads, pizzas and tapenades; the oil is also used in skincare.
💡 Did you know? Olive trees can live over 2,000 years — some trees in the Mediterranean were already ancient when the Roman Empire fell.
⚠️ Olive Tree safety note: Olives in brine are high in salt — rinse before eating. Olive oil is safe, but people allergic to pollen may react to olive tree pollen, not the fruit.
⚠️ 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.
