Damiana: Traditional Uses, Evidence and Cautions
Damiana benefits are mostly traditional claims. This leafy shrub from Mexico and Central America is used for desire, anxiety and constipation, yet a cancer center review cites no human trial in men. The diabetes and anxiety claims rest on animal studies. Protoflow lists 200 mg of damiana leaf per serving.

What is damiana used for?
Damiana is a small shrub, Turnera diffusa, whose leaves are brewed as tea or packed into capsules. Folk use covers low desire, anxiety, constipation, diabetes and kidney trouble.
A cancer center herb review lists these claimed uses and then checks them against the studies (MSK, Damiana). Most claims do not hold up well. Seeing a herb on a list of traditional uses tells you what people hoped for, not what happened.
Damiana sits on our muira puama, damiana and catuaba page with two other herbs of the same kind.
- Part used: leaf
- Traditional use: desire, anxiety, constipation
- Label amount: 200 mg per two capsules
Do damiana benefits have human evidence?
Damiana benefits have almost no human evidence in men. The review cites one small study in women that used ArginMax, a mixed product, and small studies in postmenopausal women that still need confirming (MSK, Damiana). It cites no trial in men for sexual function, testosterone, the prostate or the bladder.
A 2024 review of Brazilian plants used for male sexual problems reached a similar place. Damiana had been studied in the lab, but the proposed modes of action come from lab and animal work (Teixeira et al., J Ethnopharmacol 2024).
| Claim | Evidence cited |
|---|---|
| Sexual function | One small study of a mixed product in women |
| Diabetes | Animal studies only |
| Anxiety | Animal studies only |
| Prostate or bladder | No human data cited |
Does damiana affect blood sugar, and what are the cautions?
Damiana is claimed to lower blood sugar, but that idea rests on animal studies, so its effect in people is unknown (MSK, Damiana). The unknown is the reason for care, not a reason for comfort.
If you take diabetes medicine, a herb that might nudge blood sugar is worth a call to your pharmacist. The herb review has no dedicated side effects section, and a safety review of herbal aphrodisiacs says damiana data are few. It adds that unstandardized products can cause problems (Brunetti et al., Pharmaceuticals 2020).
Do so before use if you take insulin or diabetes pills, and keep taking prescribed medicine. Check blood sugar as your care team advises.
More cautions for the full formula are on the side effects page.

See packsHow much damiana is in Protoflow?
Protoflow lists Damiana (Leaf) at 200 mg per serving of two capsules, or 100 mg per capsule. The label does not state whether the leaf is a powder or an extract.
We found no study that tested this amount, and none that tested Protoflow. The sales page names damiana among eight herbs, while the label shows 14 actives. We explain what the herbs are said to do, and what the sources show, on the benefits page.
The label tells anyone taking medication to consult a physician before use. That includes people on diabetes medicine.

FAQ
Damiana questions
01Is damiana tea the same as damiana capsules?
Not exactly. Tea steeps the leaf in hot water, while a capsule holds dried powder or extract, so the amounts reaching you differ. Protoflow's label lists 200 mg of damiana leaf and does not say which form it is.
02Does damiana have a recognized dose?
We did not find an established dose in the sources we read. The herb review gives no dosing, and none of its cited uses come from men's trials. That is why we describe the 200 mg on the label without calling it a proven amount.
03Why do some products pair damiana with other herbs?
Makers often combine herbs with similar folk uses. The one human study cited tested a mixed product, so its result cannot be credited to damiana alone. The same applies to any multi-herb capsule.
