  The study reports oral information on the ethnomedicinal uses of plant remedies in traditional health-care among Otuo tribe of Edo State, Nigeria. Records of 51 plant species belonging to 47 genera of 34 families are presented with their local names, parts used, preparations, modes of administration, dosage and uses.

  The present study embodies data on the seed morphometrics and effect of five hormones viz., thiourea, gibberellin, coumarin, 1-naphthalene acetic acid and Indole butyric acid on the germination of Digitaria exilis. The hormonal treatment was carried out under different concentrations, time regimes and continuous light and dark conditions. The highest percentage germination (78%) was recorded in seeds treated with Thiourea (0.01 mg L-1) for 15 min and 0.0001 mg L-1 for 60 min under continuous dark condition while lowest percentage germination (25%) was recorded in seeds treated with 1-naphthalene acetic acid (0.001 mg L-1) for 60 min under continuous light condition.

  The hypotensive and acute toxicity activities of methanol extract of B. axillaris leaves, obtained by soxhlet extraction, were analyzed using animal models. The extract exhibited a dose-dependent reduction in rabbit blood pressure. Basal mean arterial pressure of 115.67 ± 3.60 mm Hg was progressively reduced to 106.22 ± 3.13 and 69.3 ± 2.59 mm Hg by 2.5 and 20 mg kg-1 doses of extract, respectively. Hematological parameters in Wister rats treated with 1, 2 and 4 g kg-1 of extract showed no significant difference, p>0.05. However, lethal dosage was obtained at 8 g kg-1. The need for further evaluation and prospect of the plant in health care was also discussed.

  This study was aimed at determining the phytochemistry and antimicrobial properties of the methanolic extract of Baissea axillaris leaf. Phytochemical analyses of B. axillaris leaf using procedures described by Trease and Evans, revealed the presence of saponins, phenolic compounds, eugenol oil, glycosides and tannins. Methanolic extract of the leaf showed antimicrobial activities against some organisms. The extract was most active against Staphylococcus aureus yielding the highest zone of inhibition (15 mm) as well as the least minimum inhibition concentration of 125 μg mL-1. It was least effective against Escherichia coli as minimum inhibition concentration was above 500 μg mL-1.

  The phytochemical analysis on stems of Stachytarpheta jamaicensis proved the presence of secondary metabolites, including; tannins, saponins and flavonoids Crude concentrations of aqueous extract of stem showed antimicrobial activity on Bacillus subtilis, Escherichia coli, Candida albicans, Staphylococcus aureus, Pseudomonas aureginosa and slight activity on Proteus vulgaris while the alcoholic extract had almost similar activity, but lesser activity was observed on Escherichia coli.
