Mate (drink)
Both the wood vessels and the gourds must undergo curing to get a better taste before being used for the first time and to ensure the long life of the gourd.  Typically, to cure a gourd, the inside is first scraped with the tip of a bombilla to remove loose gourd particles. Mate herb and hot water is added next, and the mixture poured into the gourd. The mixture is left to sit overnight and the water is topped off periodically through the next 24 hours as the gourd absorbs the water. Finally the gourd is scraped out, emptied, and put in sunlight until completely dry.
