Sage: Effect and Side Effects

Sage, especially due to the essential oil it contains, has an inhibitory effect on the growth of bacteria, viruses (including herpes virus) and fungi.

The bitter substances contained excite bitter receptors at the base of the tongue, which leads to an increase in saliva and gastric juice production, thus promoting digestion. The essential oil irritates the stomach wall, causing a slight increase in gastric and intestinal motility.

The inhibitory effect on sweat secretion is due to an influence on the heat regulation centers in the midbrain.

Side effects of sage

Side effects are usually only to be feared with overdose or prolonged use. The thujone contained in sage leaves may cause symptoms such as a feeling of heat, dizziness, increased heart rate, or convulsions.

However, side effects are not to be expected with external application or the ingestion of aqueous preparations such as the tea, since only traces of thujone are contained here.

Interactions with other agents are not currently known.
