The plant Acanthus montanus is a strikingly small
shrub with sparse branches and soft stem that
belongs to the family Acanthaceae. It is commonly
known as Mountain Thistle or Bears Breech and is
believed to have originated from West Africa [3].
Traditionally, the stem and leaves are used locally to
treat various illnesses. In Traditional Medicine and
Pharmacopoeia of Cameroon, AM is used to treat
pain, cough, epilepsy, dysmenorrhoea, miscarriages
and false labour [4]. Soups made from it are also
used for abdominal pains caused by indigestion.
Asongalem et al. [5] reported that aqueous extracts of
the plant showed anti-inflammatory, lack of central
analgesia and antipyretic properties.
