Effect of Hypericum extract on the hypothalamic-pituitary-adrenal system in rats.
We studied the effect of Hypericum extract on activity of the hypothalamic-pituitary-adrenal system in rats. In rats exposed to stress after a 30-day daily oral treatment with Hypericum extract, the weight of the adrenals and ACTH concentration were lower than in controls. Hence, treatment with Hypericum extract improved resistance to stress and prevented exhausting of the hypothalamic-pituitary-adrenal system.
