Helichrysum faradifani is one of the endemic Helichrysum in Madagascar. This species is widespread in the central and southeastern regions. The plant is used in Malagasy traditional medicine for wound-healing. Other endemic species of Helichrysum are also known for their pharmacological properties like diuretic, antidiabetic, stimulant, digestive and haemostatic agents and their antibacterial activity are also reported. Even if many species of Helichrysum have been investigated, the chemical composition of H. faradifani oils has only been reported by Cavalli et al.. They found that H. faradifani,collected in the north of the region of Antananarivo, contained mainly beta-caryophyllene and linalool (16.1%). Later research using dichloromethane extract of the leaves of this plant rather than a steam distilled oil reported seven compounds; two of which were new: 8-(3-phenyl-2-propen-1-one)-7-hydroxy-5-methoxy-2-dimethylbenzopyran and 2'-4'-6'-trihydroxy-3'-methoxydihydrochalcone.
