Mushroom Tinctures and Liquid Extracts

A tincture or liquid extract is a mushroom extract sold as a liquid, usually in a dropper bottle. Some contain alcohol, some use glycerin or water, and the label should say which. This page explains the product type only. It does not describe how to make one at home, and it is not advice to use one.

What the label should show

The FDA says supplement labels must carry a Supplement Facts panel with serving size and the amount of each ingredient per serving, except for ingredients inside a proprietary blend. [1] The FDA also says dietary supplements can be sold as liquids. [1] For a mushroom liquid, look for:

• the mushroom species and part used;
• how much mushroom material or extract is in one serving (a "drop" or "dropper" is not an amount);
• the liquid base and any alcohol content;
• other ingredients such as sweeteners and flavorings. [1]

"Dual extract" on a tincture usually means water and alcohol extracts were combined, but we did not find the term defined in the sources we read. See mushroom extracts.

Alcohol

Liquid herbal products often contain ethanol, and one review notes that the ethanol content of many liquid herbal medicines, needed for pharmaceutical reasons, has raised questions about their safety. [2] That same review analyzed data from more than 50,000 children in studies of authorized herbal medicines and found no evidence that ethanol caused adverse reactions in them. [2] Those were authorized medicines used within their labels, not mushroom supplements, so the result does not transfer to a bottle of mushroom drops.

People who may need to check the alcohol content with a pharmacist include those:

• avoiding alcohol for any reason, including recovery. See alcohol-containing herbal products;
• taking medicines that a pharmacist says should not be combined with alcohol;
• pregnant or breastfeeding, or giving a product to a child. Many supplements have not been tested in these groups. [3]

The sources we read do not give an alcohol percentage typical of mushroom tinctures, so we do not state one.

Is a liquid absorbed better than a capsule?

Proper evidence not found. We searched PubMed for studies comparing liquid mushroom extracts with capsules in people and found none. A liquid is not shown to be stronger or better than a capsule or powder. See mushroom capsules vs liquid extracts.

Quality

The sources we read describe adulteration and inaccurate labeling as problems for popular botanical products, including functional mushrooms. [4] NCCIH adds that "standardized" or "certified" does not necessarily guarantee quality. [3] Look for batch testing information; see certificates of analysis.
