Not one I ever use but according to Julia Lawless Chamomile Maroc (Ormenis multicaulis) is Antispasmodic, cholagogue, emmenagogue, hepatic and sedative. The aromatherapy uses are given as "sensitive skin, colic, colitis, headache, insomnia, irritability, migraine, amenorrhoes, dysmenorrhoea, menopause, liver and spleen congestion." Quoted from Marcel Lavabre Aromatherapy Workbook.
It should not and cannot be used as a substitue for either Chamomile Roman or Chamomile Blue (German)
Hope that helps
