Echinacea has been in the news lately, due to a series of studies that found it to be ineffective in protecting against respiratory tract infections such as coughs and colds (Grimm & Muller ’99, Barrett et al ’02, Kreutzfeld ’06). These were all randomised, double blind trials with reasonable numbers of trial subjects, so they cannot be lightly dismissed. In addition to these negative findings,...

The first synthesis of a series of ketones naturally occurring in E. pallida is described. The natural distribution of these ketones among different Echinacea species is also reported.

the effect of green tea, echinacea purpurea, rosemary extracts on dilation of oxidation and rancidity development in broiler thigh meat was studied. therefore, fresh thighs were dipped in 0.1%  alcoholic aqueous extract during 15 min and kept frozen (-20°c) until 6 months. sampling was carried out at 1, 30, 60, 90, 120,150 and 180 days of aging at -20°c. a parallel experiment with ascorbic acid...

A feeding trial was conducted for sixty continuous days to determine the effect of dietary Aloe vera and Echinacea  on immunological parameters of Shirbot (Barbus grypus) Four hundred and twenty fish weighing 50-60 g were randomly subjected to to seven different treatment, including one control  (Aloe vera and Echinacea free diet), A1 (0.1% of Aloe vera, A2 (0.2% of Aloe vera &nb...

Many of the herbaceous perennials, especially the newer cultivars of Echinacea, are poorly branching, slow to fill out the pot, and produce few propagules. Configure (6-BA, Fine Americas, Inc.), a new product recently labeled for branching of floricultural crops, was evaluated on a variety of perennials over two seasons. Configure was applied once as a foliar spray at rates of 0, 300, 600, 900 ...

Commercial producers of herbaceous ornamentals have reported that long-day plants sometimes flower under short-day conditions when the photosynthetic daily light integral (DLI) is high, but little research-based information available to support phenomenon. We grew seedlings tickseed (Coreopsis grandiflora), echinacea (Echinacea × hybrida), lavender (Lavandula angustifolia), lobelia (Lobelia spe...

The aim of the study was to determine the effect of ginseng and echinacea on the mRNA expression of IL-10, TNF-α, and TGF-β1 in healthy rats. Six-week-old male Fischer 344 rats (n = 48) were used. The animals were divided into three equal groups, as follows: control (C); ginseng (G); echinacea (E). While the C group was fed a standard rat diet (Purina) ad libitum for a period of 40 days, the G ...
