Scutellaria (skullcap) are important medicinal plants. Scutellaria baicalensis and S.barbata have been used in Chinese traditional medicine, while S. incana and S. lateriflora were used as herbal medicines by Native Americans. In this work, the essential oils of Scutellaria baicalensis Georgi, Scutellaria barbata D. Don , Scutellaria incana Biehler...

As part of our evaluation of essential oils derived from Native American medicinal plants, we have obtained the essential oils of Agastache foeniculum (Pursch) Kuntze (Lamiaceae), Gaultheria procumbens L. (Ericaceae), Heliopsis helianthoides (L.) Sweet (Asteraceae), Liatris spicata (L.) Willd. (Asteraceae), Pycnanthemum incanum (L.) Michx. (Lamiace...

The genus Monarda (family Lamiaceae) contains 22 species of which three are native to southern Alabama, M. citriodora, M. fistulosa, and M. punctata. Several species of Monarda have been used in traditional medicines of Native Americans, and this present study is part of an ongoing project to add to our understanding of Native American pharmacopeia...

Stimulant medications, such as amphetamines, lead to increased activation of osteoclast-mediated bone resorption resulting in decreased bone mass and are firstline medications for Attention-Deficit Hyperactivity Disorder (ADHD). PURPOSE: To determine the effect of stimulants on bone mineral density (BMD) and body composition in young adults with AD...

However, there ar...

The essential oil of Conoclinium coelestinum, growing wild in north Alabama, has been obtained by hydrodistillation from the aerial parts, and the oil analyzed by gas chromatography – mass spectrometry. C. coelestinum essential oil was rich in germacrene D (28.6%), (2E)-hexenal (9.5%), β-caryophyllene (7.4%), and (Z, Z)-α-farnesene (7.2%). The esse...

Helianthus species are North American members of the Asteraceae, several of which have been used as traditional medicines by Native Americans. The aerial parts of two cultivars of Helianthus annuus, “Chianti” and “Mammoth”, and wild-growing H. strumosus, were collected from locations in north Alabama. The essential oils were obtained by hydrodistil...

Literature review showed lowered bone mineral density (BMD) among methamphetamine users and in mice that were given methylphenidate. No human clinical studies have been carried out, to date, to investigate whether there is a correlation between use of psychostimulants prescribed for attention deficit hyperactivity disorder (ADHD) (in this case meth...

Extracts from the seeds of two morning glories were studied to determine their anti-microbial activity. Ipomoea alba and Ipomoea tricolor were analyzed by broth microdilution technique. I. alba extract showed very strong antibacterial activity against Enterococcus faecalis and Bacillus cereus, with minimum inhibitory concentration (MIC) values of 1...
