Subterranean termite infestations occur in every state in the contiguous United States and are responsible for damage to wooden structures in excess of two billion dollars (U.S.) annually. Essential oils have historically been used to repel insects. They have relatively low toxicity and some of them are exempt from regulation by the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). Dev...

A physical method is described for the rapid isolation of plant trichomes, with emphasis on stalked glandular types. The technique involved breaking frozen trichomes with powdered dry ice and collection of glandular heads by sieving from larger tissue fragments. This method was applied to several plants that bear similar stalked trichomes: geranium (Pelargonium), potato (Solanum tuberosum), tom...

From the aerial roots of the medicinal plant Geranium sanguineum L. a polyphenol-rich extract with strong anti-influenza activity has been isolated. To investigate its active fractions, the extract was partitioned by solvents with increasing polarity. The n-BuOH fraction contained the majority of the in vitro antiviral activity; the EtOAc fraction was the most effective one in vivo. A bioassay-...

The combination of a companion plant with cultivated is considered an interesting strategy to reduce pest pressure and, hence, the use pesticides. Although several plants from Alliaceae and Lamiaceae families are known be efficient against aphid pests, only few Geraniaceae family have been studied so far. aim this work was investigate potential effects Geranium macrorrhizum as on colonization s...

We report an experiment designed to investigate whether olfactory cues can influence people's judgments of facial attractiveness. Sixteen female participants judged the attractiveness of a series of male faces presented briefly on a computer monitor using a 9-point visual rating scale. While viewing each face, the participants were simultaneously presented with either clean air or else with 1 o...

The evaluation of 10 essential oils of geranium, Pelargonium graveolens (Geraniaceae), were all shown to have repellent activity against nymphs of the medically important lone star tick, Amblyomma americanum (L.). The biological tests were carried out using a vertical filter paper bioassay, where ticks must cross an area of the paper treated with repellent to approach host stimuli. One of the e...

BACKGROUND Geranium sibiricum L. has been used as a medicinal plant to treat diarrhea, bacterial infection, and cancer in Bulgaria, Peru, and Korea. However, its hair growth-promoting effect was not investigated so far. This study examined the effects of Geranium sibiricum L. extract (GSE) on hair growth, using in vitro and in vivo models. METHODS Antioxidant, proliferation and migration assa...

Cranesbill (Geranium species) are used traditionally as tonic, antidiabetic, antidiarrheal, antihemorrhoidal, diuretic and for the treatment of cough, fever, tonsillitis, urticaria, kidney pain and gastrointestinal ailments. The leaves of some Geranium species are consumed in traditional Turkish cousin as salad or added to pastry. In the present study, different extracts from G. psilostemon and...
