The essential oil did not show any antimicrobial activity. The extract exhibited antihyperglycaemic activity, and decreased the blood glucose level when applied in small doses; higher doses, however, increased the blood glucose level[ ].
Subchronic toxicity Subchronic toxicity testing was conducted according to World Health Organization and Organization for Economic Co-operation and Development guidelines. Repeated dose oral toxicity test method. Scientia Horticulturae 47 1—2: The situation is further aggravated by habitat destruction caused by slash-and-burn, commercial logging and firewood collection.
The feed and fluid intake increased in a dose dependent manner. The shaded floor of the rainforest or lowland secondary forest[ ].
Analysis using the Mann-Whitney test was carried out to examine the statistical significance of differences in the mean levels of the various parameters and biomarkers between the control and test groups using Graph Pad Prism 5. Free radicals, secreted by macrophages, T-cells, and natural killer cells as body defense, may still cause damage to -cells [ 3 ]. After 72 h, the organs were dehydrated in graded alcohol, cleared in xylene and embedded in paraffin.

The rhizome decoction of Costus dubius is taken to treat epilepsy; it is also a diuretic and febrifuge.
Costus afer – Useful Tropical Plants
Acute toxicity The acute toxicity study of aqueous leaf costua C. The aqueous extract of the leaves and stems showed significant antibacterial and amoebicidal activity in vitro. In vitro amoebicidal activity of some medicinal plants of the Bamun region Cameroon. The different plants extracts screened in this study possess a potential bioinhibitor of these enzymes including alkaloids, flavones, and tannins [ 24 ].
The stems are used in house construction[ ]. Biochemical and toxicological studies of aqueous extract of Syzigium costuz L Merr. The stem, seeds and rhizome contain several steroidal sapogenins, of which cosyus is the most important one. It flowers and fruits throughout the year, depending on the humidity of the soil[ ].

This is suggestive ckstus the antioxidant capacities contributed to the modification of the carbohydrate metabolizing enzyme activities. Reduction in ALB and increase in TG are indications of diminished synthetic function of the liver or might be due to impaired hepatocellular function.

These values are considered as rather very high and may have serious toxicological implications. The IC 50 values of the tested extracts were lower for methanol rhizome extract 0.
These properties were observed in an in vivo diabetic rat model. Journal List Anc Sci Life v. The presence of bioactive compounds such as flavonoids, alkaloids, phenols, and tannins may account for the antioxidant capacity and carbohydrate hydrolyzing enzyme inhibitory activity of C. Some of these bioactive components possess antioxidant activities and antidiabetic activities. In Cameroon Costus afer is a host of the African root and tuber scale Stictococcus veyssierei.
Kinetic parameters such as the Michaelis-Menten constant affinity and maximum velocity were derived from the plots. These inhibitory properties may be partially due to alkaloids and sesquiterpenes that were absent in the less active rhizome methanolic extract. Costus afer can be propagated by seed, and also by stem cuttings or rhizome cuttings.
Journal of Ethnopharmacology 6 3: Going by the result obtained in this present study, there is an indication of C. Costus afer may be hepatotoxic but non-toxic to the kidney. Right plant wrong place. The stem is strongly diuretic[ ].
The same extract showed moderate local anaesthetic activity[ ]. Another species of which the seed contains high concentrations of diosgenin is fenugreek Trigonella foenum-graecum Cosstus.
