The specific name tiglium is of obscure origin. It may come from the traditional name given by pharmacists to the seeds of the croton plant. According to one suggestion, it may be derived from the Greek tiglos, diarrhea. According to another, it may refer to one of the Maluku islands in Indonesia, ostensibly the home habitat of the species.^[3]

Croton tiglium is one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name bā dòu (Chinese: 巴豆)^{[citation needed]}. C. tiglium is known as japaala/ජාපාල or jayapala in Sinhala and used in Sinhala traditional medical system of Sri Lanka and in Sanskrit.

This is referred to as Śodhana, a general term for detoxification.^[4][5] The plant is poisonous, with the bark used as an arrow poison and the seeds used to poison fish.^[6]
