Bhang (IAST: Bhāṅg) is an edible preparation made from the leaves of the cannabis plant originating from the Indian subcontinent. It has been used in food and drink as early as 1000 BC in ancient India. Bhang is traditionally distributed during the spring festival of Maha Shivaratri and Holi. Bhang is mainly used in bhang shops, which sell the cannabis-infused Indian drinks bhang lassi and bhang thandai.
Garcia de Orta, a Portuguese Jewish physician based in Goa, wrote extensively on bangue in his Colóquios dos simples e drogas da India (1563), including its recreational use by Bahadur Shah of Gujarat and by many Portuguese. He explicitly rejected the notion of the Indian plant that produces bangue being the same as the European hemp plant (alcanave).
In 1596, a Dutchman, Jan Huyghen van Linschoten, wrote three pages on "Bangue" in a work documenting his journeys in the East. He also mentioned the Egyptian hashish, the Turkish boza, Turkish bernavi and the Arabic bursj forms of consumption. Despite the other accounts, the contemporary historian Richard Davenport-Hines lists the late-17th-century and early-18th-century British adventurer Thomas Bowrey as the first Westerner to document the use of bhang.
Using mortar and pestle, the leaves of cannabis are ground into a paste which can be added to foods. For a beverage it is mixed with milk and filtered, then often flavored with kusha grass, sugar, fruit, and various spices. In Mathura it can be found in bhang thandai and bhang lassi. Bhang is also mixed with ghee and sugar to make a purple halva, and into peppery, chewy little balls called goli (which means "tablet" as well as "pill") in Hindi. Another form is bhang chutney also called 'bhangeera ki chutney', a dish served in Kumaoni cuisine from Uttarakhand. It is made from grinding cannabis/bhang seeds with mint, tomatoes and different spices.
Bhang is part of the ancient Hindu tradition and custom in the Indian subcontinent. In some parts of rural India, people attribute various medicinal properties to the cannabis plant.
