THEVETIA PERUVIANA PDF

Both are members of the Dogbane family, but they reside in different genera and are very different plants. Read on for yellow oleander information and tips on yellow oleander care. Yellow Oleander Information Yellow oleander trees are so small that many consider them large bushes. Yellow oleander information suggests that these evergreen plants rarely get over 10 feet when cultivated, although they can get to 20 feet in the wild. The flower of yellow oleander looks like a narrow tube that flares out at the tip into five petals, twisted into a spiral shape.

Locations within which Thevetia peruviana is naturalised include many Pacific Islands Introduced, naturalised or invasive in East Africa Thevetia peruviana is naturalised in parts of Kenya A. Witt pers. Habitat Thevetia peruviana can be found in pastures, in savanna and in riparian zones banks of watercourses. Description Thevetia peruviana is a small ornamental tree which grows to about 1. The leaves are spirally arranged, linear and about cm in length Samal et al. All parts of the plant contain the milky juice.

Reproduction and dispersal This plant reproduces by seed. Locally, it is also propagated by cuttings especially for use as a live hedge. Economic and other uses Thevetia peruviana is widely grown as a garden ornamental. It is also used medicinally to some extent, though it is also known to be very poisonous. Environmental and other impacts Thevetia peruviana can be invasive in open areas and under light shade. All parts of the plants are very poisonous, especially the sap and oily seeds.

The common name be-still refers to its poisonous properties. It has been listed as a noxious weed in South Africa prohibited plants that must be controlled. They serve no economic purpose and possess characteristics that are harmful to humans, animals or the environment. Management The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species.

The best form of invasive species management is prevention. If prevention is no longer possible, it is best to treat the weed infestations when they are small to prevent them from establishing early detection and rapid response. Controlling the weed before it seeds will reduce future problems. Control is generally best applied to the least infested areas before dense infestations are tackled.

Consistent follow-up work is required for sustainable management. The editors could not find any specific information on the management of this species.

Abstract Intentional self-poisonings with seeds from the yellow oleander tree Thevetia peruviana are widely reported. Two recent randomised controlled trials RCTs assessing the efficacy of activated charcoal reported conflicting outcomes in terms of mortality. The effect of activated charcoal on the pharmacokinetics of Thevetia cardenolides has not been assessed. This information may be useful for determining whether further studies are necessary. The concentration of Thevetia cardenolides was estimated using a digoxin immunoassay. The effect of activated charcoal on cardenolide pharmacokinetics was compared between treatment groups using the AUC24, the 24h Mean Residence Time MRT24 , and regression lines obtained from serial concentration points adjusted for exposure. Erratic and prolonged absorption patterns were noted in each patient group.
