Sage for Sweating: How to Use It and Does It Help
Sage for sweating: doses from the EMA monograph, research results on hot flashes, and the mandatory warning about thujone and the 6 mg daily limit.
Common sage is one of the few herbs for which the answer is yes, but with a caveat. The European Medicines Agency allows sage leaf for alleviating excessive sweating, but in a traditional manner, based solely on long-term use, not clinical studies. Hard numerical results pertain to something narrower: hot flashes in postmenopausal women. General sweating, night sweats, and hot flashes are three different indications, and the evidence is unevenly distributed among them. Excessive sweating can also be a symptom of a disease, so the first step remains to determine the cause, not to reach for an herb. Below you will find doses directly from the monograph, sample sizes from both studies, and a warning about thujone, which cannot be overlooked with this herb.
KEY INFORMATION
• The EMA monograph allows sage leaf for alleviating excessive sweating as a traditional product, based solely on long-term use (EMA/HMPC/277152/2015).
• The dose from the monograph for the infusion is 2 g of dried leaf per 150 ml of boiling water.
• Dry extract DER 4-7:1 is dosed at 80-160 mg three times a day, and for night sweats, the monograph provides a liquid extract DER 1:3.5-5 in the amount of 1.5 ml an hour before sleep.
• If symptoms do not improve within 6 weeks of use, the monograph advises consulting a doctor.
• In an open study of 71 women, the overall severity of hot flashes decreased by 64 percent after 8 weeks, but the study had no control group (Bommer et al., 2011).
• Daily exposure to thujone from the product must be less than 6.0 mg (EMA/HMPC/277152/2015).
Does sage really reduce sweating?
It depends on which sweating you are asking about. There are clinical studies on hot flashes in menopause, including one with a placebo. For night sweats, the EMA monograph provides separate dosing, but without a study to confirm it. For primary hyperhidrosis not related to menopause, I found not a single clinical study.
Separating these three situations is more important here than usual, because in commercial descriptions they blend into one term about sweating, while the state of knowledge for each of them looks different.
Primary hyperhidrosis is excessive sweating of the hands, feet, or armpits without a disease that would explain it. Searching the European PMC database under the term sage and hyperhidrosis does not return any studies involving humans. The indication from the monograph is based solely on the tradition of use, which the monograph states directly: a traditional product for use in indications based solely on long-term use.
Night sweats have their own dose in the monograph, given an hour before sleep, which in itself indicates intended use. However, the basis for approval remains the same traditional manner, without a controlled study.
Hot flashes in menopause are the only one of these indications for which there are numerical results, and these are often stretched in advertising to all the others.
What studies support sage for hot flashes?
Two, with clearly different strengths. The first was open, without a control group. The second was randomized and placebo-controlled, but it was funded by the manufacturer of the studied preparation. Both concern postmenopausal women, not sweating as such.
In the open study, conducted in eight Swiss practices, 71 women participated, and 69 were included in the analysis. The average age was 56.4 years, and the condition for participation was at least five hot flashes per day. Participants took one tablet of fresh sage leaf extract daily for 8 weeks. The overall severity score of hot flashes decreased by 50 percent after 4 weeks and by 64 percent after 8 weeks, with p below 0.0001 (Bommer et al., Adv Ther, 2011). The lack of a control group means that this result cannot be distinguished from the placebo effect or from the natural resolution of symptoms.
The second study was double-blind and placebo-controlled. The analysis according to the intention-to-treat included 78 women aged 48 to 65, who took 280 mg of thujone-free extract or placebo for 4 weeks. The score on the hot flash severity scale decreased by 55.3 percent in the sage group, and the difference from placebo was significant from the third week, with p equal to 0.028. A decrease of at least half was achieved by 59.1 percent of women in the sage group compared to 26.9 percent in the placebo group (Dimpfel et al., Heliyon, 2021). The study was funded by the product manufacturer, and one of the co-authors is an employee of the company, which should be taken into account when evaluating the result.
How to use sage for sweating?
The doses are provided by the EMA monograph, and this is the only place where they are more than just custom. For the indication covering excessive sweating, the monograph lists infusion, dry extract, and two liquid extracts, each with its own dose and method of administration. All are taken orally.
| Form | Single Dose | Frequency | Note |
|---|---|---|---|
| Infusion of dried leaf | 2 g per 150 ml of boiling water | the monograph does not specify for this indication | oral administration |
| Dry extract DER 4-7:1 | 80-160 mg | 3 times a day | oral administration |
| Liquid extract DER 1:3.5-5 | 0.5-1 ml in liquid | 3 times a day | oral administration |
| Liquid extract DER 1:3.5-5, night sweats | 1.5 ml in liquid | once a day, an hour before sleep | separate entry in the monograph |
| Liquid extract DER 1:4.5 | 2 ml | 3 times a day | oral administration |
The monograph does not recommend use in individuals under 18 years of age. In the absence of improvement within 6 weeks, it advises consulting a doctor, while allowing long-term use for this indication (EMA/HMPC/277152/2015). We have gathered sage herb and other brewing materials in the herbs category.
Why is there a warning about thujone with sage?
Because thujone has been described as neurotoxic, and sage contains it in its essential oil. The EMA monograph requires determining the thujone content in each preparation and keeping daily exposure below 6.0 mg. It is also recommended to choose chemotypes with low content of this compound.
Where did the 6 mg limit come from? The Committee on Herbal Medicinal Products based it on modeling the reference dose from a long-term toxicity study, where the endpoint was clonic seizures. The calculated acceptable daily dose was 0.11 mg per kilogram of body weight, which is 6.6 mg for a person weighing 70 kg. About 1 mg, which is typically provided by the diet, was subtracted from this value, resulting in the exposure limit from the medicinal product (EMA/HMPC/732886/2010).
Earlier determinations were stricter. For preparations from sage leaf, there was a limit of 5 mg per person with a maximum duration of use of 2 weeks. The 2016 monograph did not maintain this time limitation for the indication of sweating: it allows for long-term use and only sets a threshold of 6 weeks for consultation in the absence of improvement. The rigor shifted from time to the composition of the preparation.
That thujone is not a theoretical threat is evident in the point of the monograph about overdose. Consumption of sage oil corresponding to more than 15 g of leaf has been described as causing a feeling of heat, increased heart rate, dizziness, and seizure-like convulsions. An infusion of 2 g of leaf is very far from this amount, but sage essential oil is a completely different product than tea, and they must not be confused.
Who should not use sage for sweating?
Pregnant and breastfeeding women, individuals under 18 years of age, and those allergic to the raw material. The EMA monograph formally lists one contraindication, which is hypersensitivity to the active substance, while other restrictions are noted as a lack of recommendation due to insufficient data.
Safety during pregnancy and breastfeeding has not been established, so due to insufficient data, the monograph does not recommend use during these periods. There is no data on its effect on fertility at all. The use in children and adolescents under 18 years of age has also not been established for the same reason.
Epilepsy requires a separate statement, as it is sometimes listed as a contraindication without citing a source. It is not on the list of contraindications in the monograph; only hypersensitivity is listed there. The basis for caution is something else: the neurotoxicity of thujone and the description of sage oil overdose with seizure-like convulsions. The public position on thujone adds that for sensitive groups, including pregnant women and children, there are no studies allowing for the assessment of exposure effects, so their exposure should be minimized. In the case of diagnosed epilepsy, leave the decision to the doctor instead of basing it on the label.

Frequently Asked Questions
Does sage help with sweating not related to menopause?
There are no clinical studies on this. The EMA monograph includes the indication for alleviating excessive sweating, but in a traditional manner, based solely on long-term use. The numerical results pertain only to hot flashes in postmenopausal women.
How to brew sage for sweating?
The EMA monograph states for this indication 2 g of dried leaf per 150 ml of boiling water, prepared as an infusion. The frequency of drinking for this indication is not specified in the monograph, unlike for digestive ailments, where it indicates three times a day.
How long does it take for sage to start working on sweating?
The monograph sets a threshold of 6 weeks: if symptoms do not improve within this time, it advises consulting a doctor. In an open study on hot flashes, the overall severity decreased by half after 4 weeks (Bommer et al., 2011).
Can sage be used long-term?
The EMA monograph allows for long-term use for this indication, referring to warnings. The condition remains to keep daily exposure to thujone below 6.0 mg, and its content must be demonstrated by the manufacturer for each batch of the product.
Does sage help with night sweats?
The monograph provides a separate dose for night sweats: a liquid extract with a ratio of 1:3.5-5 in the amount of 1.5 ml an hour before sleep. The basis remains the tradition of use, as randomized studies concerned hot flashes, not night sweats themselves.
Is sage safe during pregnancy and breastfeeding?
Its use is not recommended. Safety during pregnancy and breastfeeding has not been established, and the EMA monograph, due to insufficient data, advises against use during both periods. There is no data on its effect on fertility at all.
What are the risks of thujone contained in sage?
Thujone has been described as neurotoxic. The basis for the 6 mg daily limit was modeling based on clonic seizures in a long-term study, with a calculated acceptable dose of 0.11 mg per kilogram of body weight (EMA/HMPC/732886/2010).
Is sage safe for epilepsy?
The EMA monograph does not list epilepsy among contraindications, as it is only on the list for hypersensitivity. Caution arises from the neurotoxicity of thujone and the description of sage oil overdose, which can lead to seizure-like convulsions.
