Vanaspati (Devanagari: वनस्पति) is the Sanskrit word that now refers to the entire plant kingdom. However, according to Charaka Samhitā and Sushruta Samhita medical texts and the Vaisesikas school of philosophy, "vanaspati" is limited to plants that bear fruits but no evident flowers. In the Rigveda, 9th Mandala, Hymn 1.5, "Vanaspati" (literally meaning: Lord of the Forest) is a deity presiding over the forest and described as the "bright golden hued Vanaspati, with its thousand branches."

Charaka Samhitā and Sushruta Samhita medicine texts classify plants into Vanaspati, Vrksa or vanaspatya, Virudh and Osadhi.

These are further divided into 50 groups based on their physiological actions and diseases they cure. Flowering plants are divided into sukadhanya (cereals), samidhanya (pulses), saka varga (pot herbs), phala varga (fruits), harita varga (vegetable), ahayogi varga (oils), and iksu varga (sugarcane).
