Damiana 1000 mg, 60 Vegan Capsules

What Damiana Is
Damiana is Turnera diffusa, a small aromatic shrub from Mexico, Central America and the Caribbean, used traditionally as an aphrodisiac and as a tea. Remedy's Damiana supplies 1000 mg of leaf per vegan capsule, with 60 capsules per bottle, as a single ingredient.
It has a long tradition and a thin research base, and this page states both.


1000 mg per capsule: Single-ingredient damiana leaf.

60 capsules: Two months at 1 daily.

Contains: Flavonoids, and caffeine as a documented constituent.

Traditional use: Aphrodisiac and relaxing tea.

The full claim map is in our damiana overview.

What the Evidence Actually Shows
The definitive review of the genus is unusually direct, and we would rather print its conclusion than a benefits list.



What the review reported
Detail



Species in the genus
135 accepted, about 6 used medicinally


Bioactivities identified
12, from antianxiety to aphrodisiac


How most were tested
Chemical, cell-based or animal assays only


Human studies
2, both using multi-ingredient preparations


Compounds identified
22 flavonoids, caffeine, 7 cyanogenic glycosides


Compound linked to an effect
Apigenin, in an animal pain model




Most of damiana's reported activities have been investigated only in chemical, cell-based or animal assays, and both human studies used preparations containing other ingredients.[1]Ethnobotany, phytochemistry, and bioactivity of the genus Turnera (Passifloraceae) with a focus on damiana - Turnera diffusa — Journal of Ethnopharmacology (2014) View source That leaves no trial of damiana on its own.

The Aphrodisiac Question
This is the reputation the plant is sold on, and it deserves the two facts that actually sit behind it.



Study
What it tested
Result



Rat study, 2009
Turnera diffusa at 20 to 80 mg per kg
More males resumed a second series at 80 mg/kg


Same study
Locomotor activity and anxiety
No associated increase in either


Same study
Main compounds in the active extract
Caffeine, arbutine, flavonoids


Human trial, 2001
A formula with 6 ingredients
73.5% improved against 37.2% on placebo


That formula
Ingredients
Ginseng, ginkgo, damiana, L-arginine, vitamins, minerals




The rat result is real and it is in rats.[2]Turnera diffusa Wild (Turneraceae) recovers sexual behavior in sexually exhausted males — Journal of Ethnopharmacology (2009) View source The human result is real and it belongs to a six-ingredient formula in which damiana was one component.[3]A double-blind placebo-controlled study of ArginMax, a nutritional supplement for enhancement of female sexual function — Journal of Sex and Marital Therapy (2001) View source The detail is in is damiana an aphrodisiac.

Hormones: What We Do Not Claim
Whether damiana changes oestrogen is one of the most searched questions about it, and the laboratory answer points two ways at once.


Aromatase inhibition: The extract inhibited it, IC50 63.1 micrograms per millilitre.

Estrogenic activity: 3 compounds showed it in a yeast screen.

Both findings: In vitro, and in opposite directions.

Human hormone measurements: 0.

We make no hormone claim for this herb.[4]Anti-aromatase activity of the constituents from damiana (Turnera diffusa) — Journal of Ethnopharmacology (2008) View source The reasoning is in damiana for women and hormones.

How to Use It
There is no established dose, because there is no human trial of damiana on its own.



Question
Practical answer



How much
1 capsule of 1000 mg daily, per the label


When
Earlier in the day, since caffeine is a constituent


With food
Either; food helps if it upsets your stomach


Bottle life
2 months at 1 daily


Trial dose in humans
None exists




Amounts and why no conversion is possible are in dosage and how to take it.

Safety and Who Should Avoid It
With no large human safety trial, the honest cautions come from tradition and from what the plant contains.



Situation
Position



Pregnant or planning pregnancy
Avoid; Turnera species are traditionally used as abortives


On glucose-lowering medication
Ask first; antidiabetic activity is reported in animals


Liver disease
Ask, as with any herbal product


Caffeine sensitive
Avoid an evening dose


Heavy daily tea drinking
Moderate it; the genus contains 7 cyanogenic glycosides


Smoking or vaping the leaf
We do not recommend it; 0 studies support it




The full list is in side effects and who should avoid it.

Capsules, Tea and the Rest
Tea is how most people meet damiana, and it is searched far more than the capsule.


Capsule: 1000 mg, identical every time.

Tea: Varies by leaf, amount and steeping.

Liqueur: A culinary use, not a medicinal one.

Smoking blends: 0 studies, and we do not recommend it.

Brewing and tradition are in damiana tea benefits and how to make it, and the intoxication question in does damiana make you high.
