Croton and Artanema are both a what?
Croton (plant) Croton is an extensive flowering plant genus in the spurge family, Euphorbiaceae. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to "Codiaeum variegatum". The generic name comes from the Greek κρότος ("krótos "), which means "tick" and refers to the shape of the seeds of certain species.
Croton oil Croton oil ("Crotonis oleum") is an oil prepared from the seeds of "Croton tiglium", a tree belonging to the order Euphorbiales and family Euphorbiaceae, and native or cultivated in India and the Malay Archipelago. Small doses taken internally cause diarrhea. Externally, the oil can cause irritation and swelling. Croton oil is used in some chemical peels, due to its caustic exfoliating effects it has on the skin. Used in conjunction with phenol solutions, it results in an intense reaction which leads to initial skin sloughing. Since croton oil is very irritating and painful, it is used in laboratory animals to study how pain works, pain-relieving and anti-inflammatory drugs, and immunology.
