Background: Acanthus montanus Nees T. It is used in African traditional medicine for the treatment of urogenital infections, urethral pain, endometritis, urinary disease, cystitis, leucorrhoea, aches and pains.
In southeastern Nigeria, the root is popular and acclaimed highly effective in the treatment of furuncles. This study was undertaken to experimentally evaluate the antimicrobial and anti-inflammatory properties of the root extract as well as its effect on phagocytosis and specific cell-mediated immune response which may underlie the usefulness of the roots in treatment of furuncles.
Methods: The aqueous root extract obtained by hot water maceration of the root powder was studied for effects on the growth of clinically isolated strains of Pseudomonas aeruginosa and Staphylococcus aureus. The anti-inflammatory activity was investigated using acute topical edema of the mouse ear induced by xylene, acute paw edema induced by agar in rats, formaldehyde arthritis in rats, vascular permeability induced by acetic acid in mice and heat- and hypotonicity-induced haemolysis of ox red blood cells RBCs.
Also evaluated were the effects on in vivo leukocyte migration induced by agar, phagocytic activity of macrophages on Candida albicans and specific cell-mediated immune responses delayed type hypersensitivity reaction DTHR induced by sheep red blood cell SRBC. The acute toxicity and lethality LD50 in mice and phytochemical constituents of the extract were also determined.
It also inhibited vascular permeability induced by acetic acid in mice and the haemolysis of ox RBCs induced by heat- and hypotonicity. Phytochemical tests on the extract revealed an abundant presence of alkaloids and carbohydrates while saponins, glycosides, and terpenoids occurred in trace amounts. Conclusion: The effectiveness of the root of A. Antimicrobial and anti-inflammatory activities are likely contributory mechanisms.

Acanthus montanus T.Anderson
Gardening Help Search. Winter hardy to USDA Zones where it may be grown in fertile, medium moisture, well-drained soils in full sun to part shade. Plants tolerate a wide range of soils except poorly-drained ones. Plants may not flower well in too much shade. Remove flowering stalks after bloom. Plants are evergreen in warm winter locations, but leaves will show considerable damage in colder winters near the northern edge of the growing range. Plants can spread invasively by creeping rootstocks, particularly in loose soils.
Acanthus montanus Nees T. It is a native of West Africa and has been introduced to the rest of the world as an ornamental plant. In Malaysia it has become feral and seems to colonise riverside areas in the North-west of Peninsular Malaysia. It is an erect, prickly perennial that can grow up to 2m tall. The stem is stout woody and sparsely branching. Leaves are opposite, glossy and papery in texture, deeply pinnately-lobed, up to 20cm long and 10cm wide.
