In this study, it was aimed to examine and compare the effects of Hibiscus (Hibiscus sabdariffa L.) poppy (Papaver rhoeas extracts on some chemical, physical, microbiological sensory properties bread dough bread. The pH, L, b, chroma, hue values decreased by usage hibiscus extract, while a value increasing. It determined as lowest pH 4.13; L 39.23; b 5.08; chroma 6.55, angle 54.65 highest 7.20....

The effects of a 90-day oral administration of water and alcohol extracts of dried calyx of Hibiscus sabdariffa were evaluated in albino rats. Haematological, biochemical and histopathological changes were monitored every 30 days. The death of the animals was preceded by a severe loss in weight, accompanied with diarrhoea in animals on the 2000 mg/kg dose. There was an increase in food intake (...

Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including antican...

The effects of aqueous extract and anthocyanin-rich extract of the calyces of Hibiscus sabdariffa Linn on the 2,4-dinitrophenylhydrazine (DNPH)-induced changes in the levels of antioxidant enzymes of rabbits were evaluated in this study. The organs examined were the blood, brain and liver. Exposure of rabbits to DNPH (28 mg/kg body weight) caused significant (P<0.05) increase in catalase and su...

In order to compare the antihypertensive effectiveness and tolerability of a standardized extract from Hibiscus sabdariffa with captopril, a controlled and randomized clinical trial was done. Patients from 30 to 80 years old with diagnosed hypertension and without antihypertensive treatment for at least 1 month before were included. The experimental procedure consisted of the administration of ...

This study evaluated immunomodulatory properties and the sub-acute toxicity profile of two fractions of the aqueous alcoholic extract of the dried calyx of Hibiscus sabdariffa in experimental animals. Immunomodulatory activity was evaluated using red blood cell-induced immunostimulation. The fractions were not found to be toxic after 7-day administration, though there was severe weight loss wit...

The aqueous calyx extract of Hibiscus sabdariffa (HS) has a folk reputation as an antihypertensive agent. On account of its antioxidant properties and probably high K+ concentration, we hypothesized that HS may attenuate the development of salt-induced hypertension. Sprague-Dawley rats (n=8 each) were treated for 12 weeks as follows: control (normal diet + water), salt-loaded (8% salt diet + wa...

The effects of aqueous extract of Hibiscus sabdariffa calyces on haematology and pathological changes in some selected organs during experimental Trypanosoma congolense infection of rats were investigated. Three groups of rats were intraperitoneally infected with T. congolense (Karu stock). One group was administered with the aqueous extract and another given a solution of vitamin C in drinking...
