💊 Lettuce in the medicine industry
Lettuce is hydrating and low-calorie; its latex was historically used as a mild sedative, and modern varieties are prized mainly for fresh nutrition and fibre.
🌱 Growing & care tips
Lettuce is the easiest salad crop — sow in cool weather, keep soil moist, and pick leaves as needed; it bolts in heat, so summer crops need shade.
🍽️ How to use it
Lettuce is eaten fresh in salads, wraps and burgers; romaine hearts are grilled; butterhead leaves are soft enough for baby food.
💡 Did you know? Lettuce belongs to the daisy family — if you let it bolt, it grows a tall stem of small yellow daisy-like flowers.
⚠️ Lettuce safety note: Lettuce is safe and gentle; because it is 95% water it carries little nutrition — wash leaves well to remove soil and pesticides.
⚠️ 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.
