Lehya is the paste form of medicine which is having equally medicinal property and the rasayana property(rejuvenating property). It is prepared by processing the kwatha(decoction) with choorna and herbal preservatives. For example in Chayavanaprasa lehya  boiled gooseberry grinded to pasty form and mixed with a kwatha prepared from more than 60  drugs and choornas.
