Objective Scoparia dulcis, a widely used medicinal plant is believed to have antihypertensive effects among traditional medical healers. This study investigates the efficacy of Scoparia dulcis as an antihypertensive agent in Wister rats. Methods Plant specimens were collected from local gardens in Portharcourt and identified in Department of plant Science, University of Portharcourt. Methanol and aqueous extracts were made from the leaves of the plant. Phytochemical screening was done using conventional methods and acute toxicity studies carried out to determine the LD 50 using the Arithmetic method of Karber. Rats were anaesthesized using urethane, and endotracheally-intubated. The rats were then cannulated via the jugular vein and carotid artery. The carotid artery was connected to a pre-calibrated Ugo Basile double channel pen recorder. Adrenaline (0.5µg/kg), Acetylcholine (1.5µg/kg), and 20, 40, 80 and 160mg/kg of the aqueous and methanol extracts were administered through the jugular vein and their effects on the blood pressure (BP) and heart rate (HR) recorded. The mean arterial pressure (MAP) was calculated. This was repeated in four series for each extract and the mean of all experiment ± standard error of mean calculated. Results were analyzed statistically using Kruskal-Wallis, Dunn's and Tukey-Kramer multiple comparisons test and Friedman nonparametric test. Results The phytochemical analysis reveals the presence of Tannins, Phlobatannins, Steroids, Terpenoids, Flavonoids and Cardiac glycosides in the leaves of Scoparia dulcis. There were no Saponins. The LD 50 was 450 and 650mg/kg for the methanol and aqueous respectively. There was significant (P<0.05) hypertensive and sympathomimetic effects at 40, 80 and 160mg/kg dose levels for both extracts. Discussion Though, Scoparia dulcis plant is used traditionally in the treatment of hypertension, scientific research has not demonstrated this property but rather has shown this plant to increase the BP, MAP and HR as revealed by the above results. The plant contains catecholamines which accounts for these effects after parenteral administration. In the traditional medicine system, there are no scientific means of diagnosis of hypertension such as measurement of BP, other than perceived symptoms such as headache, insomnia and malaise. Extracts of Scoparia dulcis plant are reported to have analgesic, anti-inflammatory and sedative effects and it is likely that the improvement in the above symptoms in hypertensive patients that is erroneously believed to be the BP lowering effects among traditional medical healers.

Honey is a delicious viscous sweetener made naturally by bees for their own nourishment. Honey comes in a range of colours including white, amber, red, brown and almost black. Honey is a mixture of sugars and other compounds. With respect to carbohydrates, honey is mainly fructose (38.2%) and glucose (31.1%) though others include maltose, sucrose and complex carbohydrates (Anon, 1995). Honey is known to exhibit a broad spectrum of activities including antiviral, antibacterial and immunostimulant (Molan, 2002; Mato, et al., 2003). It was found to have antioxidant activity due to its high content of flavonoid (Mabrouk, et al., 2004). Honey has been found to have a hepatoprotective activity against methyl nitrosoureainduced oxidative stress and inflammatory response in rats by 100% by keeping normal defense system
