Frostblade

Frostblade is an herb mostly found in dunes. It is one of the most commonly used ingredients in Herblore, and therefore scarce by demand. The edge of the leaves consist of a layer of a solid white salt, both salty and sour in flavor. When used in a potion and consumed, the plant seems to clear the mind, consolidating one's consciousness, like vapour sublimating into a block of ice. It gives an icy sensation in the temple area. When used in Cooking, the consumer becomes immune to heat.
