ABSTRACT:
An antihistaminic substance comprising an extract from a plant tissue of Stevia, which is primarily contained in its stems and leaves, and in a cold water, hot water or lower alcohol extract thereof. Standing of the extract naturally causes fermentation to separate one or more organic acids such as lactic acid and acetic acid, thereby more enhancing the antihistaminic action. The addition of at least one organic acid to the extract immediately after extraction can also enhance the antihistiminic action. When rainbow trout or broilers are fed diets containing histamine, this extract significantly relieves the action of histamine. The extract also represses symptoms such as flare, itch and pain caused by excessive release of activated histamine or a histaminic substance, thus providing an antihistaminic substance of natural origin having no side effects.
