En Español (Spanish Version)The herb sage has a long history of use in food and medicine. In Mediterranean cultures it was used internally to treat excessive menstrual bleeding, increase fertility, aid memory, reduce symptoms of arthritis, and reduce breast engorgement during weaning. It was used topically for treatment of wounds, sprains, and muscle injuries, and as a gargle for sore throat, hoarseness, and cough.
Sage has been approved by
Germany’s Commission E
for internal use in the treatment of
dyspepsia
(non-specific digestive distress) and excessive sweating, and for topical use in the treatment of inflammation of the mucous membranes of the throat and nose. However, only
double-blind
, placebo-controlled studies can prove that a treatment really works, and no studies of this type have been performed using sage for any of these purposes other than sore throat. (For information on why such studies are essential, see
Why Does This Database Rely on Double-blind Studies?)
A double-blind study of 286 people found that a throat spray made using sage at a 15% concentration significantly reduced
sore throat
pain as compared to placebo.
Additionally, in double-blind trials performed in Iran, 42 people with
Alzheimer’s disease
were given either a sage extract or placebo for 4 months.

The results appeared to suggest a modest improvement in mental function in the sage group as compared to the placebo group.
In another double-blind, placebo-controlled study, either placebo or sage essential oil was given to 24 healthy people using a crossover design.

The results showed possible improvement in some, but not all, aspects of
mental function
, but the design of the study was such that the results are difficult to trust. The same was true for another small study involving 20 older healthy subjects who took various doses of sage extract. Short term benefit was seen at a dose of 333 mg per day.

A similar sized study (with similar flaws) found weak hints that sage leaf might improve mood and reduce
anxiety
level.

Much weaker evidence, too weak to rely upon at all, hints that sage might have

immunomodulatory (alters immune function),

and anti-inflammatory activity.

One study failed to find that sage cream provided more than at most exceedingly modest benefits for treatment of
herpes
.

For use as tea or gargle, 1–3 grams of dried sage is steeped in a cup of water, and taken three times daily. The equivalent dose of tincture or extract may also be used
As a widely used food spice, sage is thought to have a relatively high level of safety. However, comprehensive safety studies have not been performed. Sage essential oil contains the neurotoxic substance thujone. Maximum safe doses in young children, pregnant or nursing women, or people with severe liver or kidney disease have not been established.
