Systematic reviews and meta-analyses represent the uppermost ladders in the hierarchy of evidence. Systematic
reviews/meta-analyses suggest preliminary or satisfactory clinical evidence for agnus castus (Vitex agnus castus)
for premenstrual complaints, flaxseed (Linum usitatissimum) for hypertension, feverfew (Tanacetum
Herbal medicines are mixtures of more than one active ingredient. The multitude
of pharmacologically active compounds obviously increases the likelihood of
interactions taking place. Hence, the likelihood of herb–drug interactions is
theoretically higher than drug–drug interactions, if only because synthetic drugs
Livestock production both contributes to and is affected by climate change. In addition to the physiological effects of higher temperatures on individual animals, the consequences of climate change are likely to include increased risk that geographically restricted rare breed populations will be badly affected by disturbances.
Plant latex is a complex environment. Occurring in hundreds of plant species and contained in a tube system called laticifers, latex is a milky sap with a diverse composition that includes alkaloids, terpenoid compounds, other secondary metabolites and a number of enzymes.

The effects of climate change are controversial. This paper reviews the effects of climate change on livestock following the theory of global warming. Although, the effects of global warming will not be adverse everywhere, a relevant increase of drought is expected across the world affecting forage and crop production.
