The herb is a plant in Survival: Beginnings.
Herbs are not all that common, but not all that useful. Herbs are a leafy shade of green and grow vertically in groups. They don't have many uses, but they make good decorations for a pond!
Their main use is that they restore vitality, which may have been reduced by swimming, or eating and drinking items, which reduce your vitality. The only downside is that herbs may take away some portions of water from you, as it is considered that it is spicy.
Some uses for herbs are launching them in catapults, using them to smelt ores or cook food, or helping with fires.
