Who should be careful with tinctures
A tincture is an alcohol-based extract in the EU monographs we read, and the EU requires ethanol labeling where it is present. [1] The alcohol matters for pregnancy, breastfeeding, children, people avoiding alcohol and people taking medicines that interact with alcohol. Ask a pharmacist. A hospital study found that some liquid pediatric medicines contained enough ethanol to raise a child's theoretical blood alcohol, and advised clinicians to consider ethanol content in children. [2] See alcohol in herbal extracts and the medication interactions guide.What a tincture is
EU regulators list tinctures among herbal preparations, alongside extracts, powdered herbs and essential oils. [3] In the EU monographs we read, tinctures are written as a ratio of herbal substance to extraction solvent, with ethanol as the solvent. Examples:| Herb (plant part) | Tincture as listed in the EU monograph |
|---|---|
| Ginger, Zingiber officinale Roscoe (rhizome) | Ratios 1:10 and 1:2, ethanol 90% V/V [4] |
| Lemon balm, Melissa officinalis L. (leaf) | Ratio 1:5, ethanol 45-53% V/V [1] |
| Valerian, Valeriana officinalis L. (root) | Ratios including 1:8 with ethanol 60% and 1:5 with ethanol 70% [5] |
Plant names were checked against the GBIF backbone (accepted names). [6] These are descriptions of products that EU regulators accept as traditional or well-established medicines; they are not recommendations for a reader.
Why two tinctures of the same herb can differ
The table shows that the ratio and the alcohol strength both vary by herb and by product. A study of 23 commercial peppermint tinctures sold in pharmacies in Poland found extremely diverse levels of the compounds it measured. [7] That is one herb in one country, but it shows why a label name alone does not describe what is in the bottle. Ratios are explained in extract ratios.Tincture versus tea
A tea is made with water. A tincture uses an alcohol solvent, so the two are different products even from one plant. Results from a tea study do not transfer to a tincture, or the reverse. Proper evidence not found: a PubMed search for a trial or study comparing a tincture with the tea of the same herb returned no such comparison. [8] See tincture versus extract and the overview.Frequently asked questions
What is a tincture?
In EU documents, an extract listed with a ratio of herb to extraction solvent, with ethanol as the solvent in the monographs we read. [4][1][5]
How much alcohol is in a tincture?
It varies. The EU monographs we read list ethanol from 45-53% V/V (lemon balm) to 90% V/V (ginger). [1][4] Alcohol content of tinctures sold as supplements is not described in the sources we read; check the label.
Is a tincture safe in pregnancy?
The monographs we read say safety in pregnancy has not been established or advise avoiding use as a precaution. [1][4] Ask a clinician or pharmacist.
Are tinctures safe for children?
Not established in the monographs we read; the ginger monograph does not recommend use under 18. [4] Keep tinctures out of reach; if a child swallows one, call Poison Help at 1-800-222-1222 (US).
Do tinctures work better than tea?
Proper evidence not found: a PubMed search for a comparison of tincture and tea found none. [8] They are different preparations, and a result for one does not apply to the other.

Safety notes from the monographs
- Children. The ginger monograph says use is not recommended below 18 years because of insufficient safety and efficacy data. [4]
- Pregnancy and breastfeeding. The lemon balm monograph says safety has not been established. [1] The ginger monograph says it is preferable to avoid use during pregnancy as a precaution. [4]
- Before surgery. Tell the surgical team about all supplements and extracts. See supplements before surgery.
- Home making. We give no tincture-making instructions.
