Alopecia, which is defined as the loss of hair from the body, encompasses a wide range of hair loss disorders, including alopecia areata and androgenetic alopecia. There is a growing use of botanical sources in dermatology. Accordingly the interest in the use of botanical and natural products for the treatment of alopecia is growing. Here we present a systematic review of natural and botanical ...

6-prenylnaringenin (6pn) is a chiral prenylflavonoid found most prevalently in hops ( humulus lupulus ) and present in hops and hop products. it is an isomer of the potent phytoestrogen, 8-prenylnaringenin. an enantiospecific method for quantitation 6pn by lc-esi-ms has been developed. baseline enantiomeric resolution of 6pn was attained on a chiralpak ® ad-rh column with an isocratic mobile ph...

BACKGROUND The evidence on the safety of topical preparations containing botanical extracts is limited. OBJECTIVES To assess (i) the use of botanically derived compounds in a large population, (ii) the incidence of cutaneous side-effects, and (iii) the diagnostic usefulness of patch testing. METHODS A questionnaire was used in 2661 patients to assess both the prevalence and type of topical ...

are there, Blumenthal said; it's just a matter of knowing where and how to find them. But Schardt defended the desire to reproduce such studies in U.S. labs, pointing out that, for example, European studies on the efficacy of St. John's wort for treating depression average a length of only five weeks-even though St. John's wort can take as long as four weeks to have any effect. He also asserted...

Five varieties of napiergrasses (Pennisetum purpureum) were fractionated botanically into leaf blade, leaf sheath, stem and head. Chemical composition of each of whole napiergrass and their botanical fractions were determined. Correlation, linear and multiple regressions between botanical fractions and nutritive value of varieties of napiergrass were also estimated. All botanical fractions diff...

Kew Gardens in London opened last month the first gallery in the world to open all year round dedicated to botanical illustrations. The gallery will showcase art from Kew’s unique historic collections as well as Shirley Sherwood’s contemporary collection of botanical art. The two collections, which complement each other, will allow Kew to show to the public many of its largely unseen works and ...
