Cucumber (Cucumis sativus L.) is cultivated throughout the world as an important vegetable. This review offers an insight on the versatile use of cucumbers for cosmetic, culinary and therapeutic purposes. Epidemiological and nutritional studies have shown various benefits associated with the use of cucumber. As cosmetic, cucumber is popularly used for natural beautification and for skin treatments. As a vegetable, cucumber is the quintessential materials and indispensable for salads, soups and smoothie with diverse health benefits including weight loss, remedy for chronic constipation, anti-inflammatory, cardiovascular and cancerous diseases among others. The use including weight loss, cosmetic, culinary and therapeutic purposes.

The hepatoprotective effect of onion and garlic extracts on cadmium (Cd)-induced oxidative damage in rats is reported. Control group received double-distilled water alone. Cd group was challenged with 3CdSO(4).8H(2)O (as Cd; 1.5 mg/kg bw per day per oral) alone, while extract-treated groups were pretreated with varied doses of onion and/or garlic extract (0.5 and 1.0 ml/100 g bw per day per oral) for a week and thereafter co-treated with Cd (1.5 mg/kg bw per day per oral) for 3 weeks. Cd caused a marked (p < 0.001) increase in the levels of lipid peroxidation and glutathione S-transferase, whereas glutathione, superoxide dismutase, and catalase levels were decreased in the liver. We also observed a decrease in hepatic activities of alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase and a concomitant increase in the plasma activities of ALT and AST. Onion and garlic extracts significantly attenuated these adverse effects of Cd. Onion extract proffered a dose-dependent hepatoprotection. Our study showed that Cd-induced oxidative damage in rat liver is amenable to attenuation by high dose of onion and moderate dose of garlic extracts possibly via reduced lipid peroxidation and enhanced antioxidant defense system that is insufficient to prevent and protect Cd-induced hepatotoxicity.

Cadmium (Cd) is known to exert gonadotoxic and spermiotoxic effects. The present study was performed to assess the possible protective roles of onion (Allium cepa Linn) and garlic (Allium sativum Linn) extracts on Cd-induced testicular damage and spermiotoxicity. The control group received double distilled water; Cd group received Cd (1.5mg/100g BW/day) orally; extract-treated groups were pre-treated with varied doses of onion and/or garlic extract (0.5ml and 1.0ml/100g BW/day) orally for one week and then simultaneously challenged with Cd (1.5mg/100g BW/day) for additional three weeks. Testicular tissue oxidant/antioxidant status and sperm characteristics were determined. Cd caused a marked (p

The hepatoprotective effect of methanolic extract of the leaf of Phyllanthus amarus (P. amarus) against ethanol-induced oxidative damage was investigated in adult male Wistar albino rats. P. amarus (250 and 500 mg/kg/day) and ethanol (5 g/kg/day, 20% w/v) were administered orally to animals for 4 weeks and 3 weeks, respectively. Ethanol treatment markedly decreased the level of reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) in the liver, which were significantly enhanced by P. amarus treatment. Glutathione-S transferase (GST), which was increased after chronic ethanol administration, was significantly reduced by P. amarus treatment in the liver. Also, P. amarus significantly increased the activities of hepatic alanine transaminase (ALT) and aspartate transaminase (AST) as well as alkaline phosphatase (ALP), with a concomitant marked reduction in the plasma activity of the transaminases in the ethanol-challenged rats. Lipid peroxidation level, which was increased after chronic ethanol administration, was significantly reduced in the liver by P. amarus co-treatment. Results show that P. amarus leaf extract could protect the liver against ethanol-induced oxidative damage by possibly reducing the rate of lipid peroxidation and increasing the antioxidant defence mechanism in rats.

Cadmium (Cd) is a well-known nephrotoxicant inducing kidney damage via oxidative stress. Since kidney is the critical target organ of Cd toxicity, this study was designed to evaluate the protective effects of onion (Allium cepa L.) and garlic (Allium sativum L.) aqueous extracts on Cd-induced renal oxidative stress in male Wistar rats. The control group received double distilled water alone and Cd group was challenged with 3CdSO4 · 8H2O (as Cd) (1.5 mg/100 g bw/day per oral) alone. Extract-treated groups were pre-treated with varied doses (0.5 ml and 1.0 ml/100 g bw/day per oral) of onion and/or garlic extract for 1 week after which they were co-treated with Cd (1.5 mg/100 g bw/day per oral) for 3 weeks. The results showed that the levels of renal lipid peroxidation (LPO) and glutathione-S transferase (GST) were significantly (P

Summary Cadmium (Cd) has been implicated in increased prostate gland malignancy risk in both wildlife and humans. This study examines the chemoprotective roles of onion and garlic extracts on Cd-induced biochemical alterations in the prostate glands of rats. Adult male Wistar rats were randomly divided into nine groups: control group received double distilled water; Cd group received Cd alone (1.5 mg/100 g bwt per day); extract-treated groups were pre-treated with varied doses of onion and/or garlic extract (0.5 ml and 1.0 ml/100 g bwt per day) for 1 week and then co-treated with Cd (1.5 mg/100 g bwt per day) for additional 3 weeks. Oxidant/antioxidant status and acid phosphatase (ACPtotal and ACPprostatic) activity were examined in prostate glands. Cd intoxication caused a marked (P

BACKGROUND Despite growing claims of functional health benefits in folkloric medicine, the safety of chronic/elevated intakes of onion and garlic cannot be assumed. Therefore, this study assesses oral administration of varied doses of onion and garlic on some biomarkers of hepatic and renal functions in rats. METHODS Animals were divided into five groups: control group received vehicle and extract-treated groups received varied doses of onion or garlic extract (0.5 mL and 1.0 mL/100 g bwt/day) for 6 weeks. RESULTS Both doses of onion caused marked (p
