Aak/Akada (Calotropis procera) a spreading shrub about 6 – 10 feet in height with grey-green leaves and waxy purple-white flowers. The plant yields a milky-white latex that is used to cure skin ailments including leprosy. The leaves and roots are used in traditional forms of medicine for treating cough, fever and malaria. Flowers are used to treat cholera. Self-medication is, however, dangerous as the plant contains several toxins. Direct contact with latex can lead to serious skin allergies and was once used to poison arrows. Aak fibres have been used for weaving a rough cloth and for filling pillows. The shrub grows wild in wastelands and on garbage heaps in dry, sandy conditions. The plant has been associated with sun worship in several ancient civilizations.
