Several herbs have clinical evidence supporting their use for female sexual desire, though the strength of that evidence varies widely. Ashwagandha, maca root, and tribulus terrestris have the most promising trial data, while others like ginseng and ginkgo biloba show weaker or mixed results. Most studies report noticeable improvements after four to twelve weeks of consistent use.
What drives low libido in women is rarely one thing. Stress hormones, fluctuating estrogen levels, reduced blood flow to genital tissue, and neurotransmitter imbalances all play a role. The herbs with the best evidence tend to work on more than one of these pathways, which is part of why they show up repeatedly in research.
Ashwagandha
Ashwagandha has the cleanest clinical data for female sexual function among the commonly discussed herbs. In a randomized, placebo-controlled trial of 80 healthy women, those taking 300 mg of ashwagandha root extract twice daily for eight weeks saw significant improvements across every domain of sexual function measured: desire, arousal, lubrication, orgasm, satisfaction, and pain during sex. Their overall sexual function scores jumped from 14.20 at baseline to 22.62 at week eight, compared to a smaller increase (14.17 to 19.25) in the placebo group.
The women taking ashwagandha also reported more satisfying sexual encounters at both four and eight weeks compared to placebo. This herb is best known for lowering cortisol, the body’s primary stress hormone. Since chronic stress is one of the most common suppressors of sexual desire in women, that stress-buffering effect likely accounts for much of its benefit. The study specifically enrolled women without hormonal disorders, suggesting ashwagandha works even when hormone levels are technically normal.
Maca Root
Maca is probably the most widely marketed herb for female libido, and the evidence is real but more nuanced than supplement labels suggest. A 12-week, double-blind trial tested 3 grams per day of maca root in 45 women experiencing sexual dysfunction caused by antidepressant medications (SSRIs and SNRIs). The overall improvement in sexual function scores was not statistically significant compared to placebo. However, a higher percentage of women in the maca group reached meaningful recovery thresholds: 30% of maca users hit a key sexual function benchmark versus 20% on placebo.
The researchers noted maca appeared to help more with orgasm difficulties than with desire specifically, and that the benefits were more apparent in postmenopausal women. An earlier open-label study (where participants knew they were taking the real supplement) had shown stronger results, particularly at higher doses. This pattern, where open-label results look better than blinded ones, suggests some of maca’s reputation may be amplified by placebo effects. Still, at 3 grams daily, it appears to offer modest benefits for some women, particularly those whose sexual difficulties are linked to antidepressant use.
Tribulus Terrestris
Tribulus terrestris has a long history in traditional medicine systems across Asia and Eastern Europe. A systematic review of clinical trials found that both premenopausal and postmenopausal women taking tribulus for one to three months showed significant increases in overall sexual function scores. In one trial of 67 premenopausal women, those taking tribulus had meaningfully higher scores for arousal, lubrication, orgasm, and satisfaction after just one month, though interestingly, desire scores did not improve significantly in that particular study.
A separate trial in 60 postmenopausal women found significant improvements in sexual function after three months. The review authors rated the overall certainty of evidence as “very low,” which in research terminology means the results are promising but the studies were small and had methodological limitations. Tribulus contains compounds called saponins that may influence androgen receptors, which could explain its effects on arousal and physical responsiveness even when subjective desire doesn’t change as dramatically.
Shatavari
Shatavari (the root of Asparagus racemosus) is a staple of Ayurvedic medicine for women’s reproductive health. Its primary active compounds are steroidal saponins called shatavarins, along with the antioxidant quercetin. What makes shatavari distinctive is its high concentration of phytoestrogens, plant compounds that can bind to estrogen receptors in the body and mimic some of estrogen’s effects.
This matters most for women in perimenopause or menopause, when the body’s own estrogen production drops. Phytoestrogens essentially occupy vacant estrogen receptors and provide mild estrogenic stimulation, which can help with vaginal dryness, reduced blood flow to genital tissue, and the general decline in sexual responsiveness that many women experience during this transition. Clinical trials have focused more on broad menopausal symptom relief than on libido specifically, so the evidence for shatavari’s sexual benefits is more indirect than for ashwagandha or tribulus.
Ginseng
Korean red ginseng is frequently recommended for female libido, but the evidence in women is weaker than its reputation suggests. A meta-analysis examining ginseng’s effects on menopausal women’s sexual function found that while some individual studies reported improvements, the changes were generally not statistically significant compared to placebo. In one crossover trial of 32 menopausal women taking 3,000 mg of Korean red ginseng daily for eight weeks, overall sexual function scores rose slightly but not enough to be distinguished from placebo effects. Another trial in postmenopausal women using a different ginseng preparation found no significant changes in sexual function scores.
Ginseng does improve blood flow through nitric oxide pathways, which is the same basic mechanism behind prescription treatments for sexual arousal disorders. It’s possible the doses tested in women’s trials were insufficient, or that ginseng’s vascular effects are more pronounced in men. For now, the data doesn’t strongly support ginseng as a first-choice herb for female libido.
Ginkgo Biloba
Early, uncontrolled studies generated excitement about ginkgo biloba for antidepressant-related sexual dysfunction in women. One open trial reported that ginkgo was effective in 91% of women with antidepressant-induced sexual side effects at doses of 40 to 60 mg twice daily. But when researchers tested this more rigorously, the results fell apart. A controlled study of 99 women found that neither a single dose nor longer-term use of ginkgo extract meaningfully improved physiological or subjective sexual arousal beyond what placebo achieved. The effect was equally unimpressive whether or not the women were taking antidepressants. Based on the stronger evidence, ginkgo does not appear to reliably help with female sexual difficulties.
Fenugreek
Fenugreek has drawn interest because of its potential to influence testosterone levels, which play a role in sexual desire for women just as they do for men. However, the best-designed trial on fenugreek and testosterone was conducted in 95 men aged 40 to 80, where the highest dose (1,800 mg daily) produced a 12.2% increase in free testosterone index over 12 weeks. No subjective improvements in sexual function were reported even with that hormonal change, and comparable data in women is lacking. Some smaller studies in women have suggested benefits for desire, but the evidence base is too thin to draw firm conclusions. Fenugreek’s role in female libido remains plausible but unproven.
How Long Before You Notice Results
Most clinical trials showing benefits ran for four to twelve weeks before measuring outcomes. Ashwagandha showed measurable improvements at four weeks with further gains by eight weeks. Tribulus terrestris produced results in as little as one month in premenopausal women, while postmenopausal women needed three months. Maca was tested over 12 weeks. Expecting overnight results from any herbal supplement is unrealistic; consistent daily use for at least a month is a reasonable minimum before evaluating whether something is working for you.
Safety Considerations
Most of these herbs are well tolerated at the doses used in clinical trials, but that doesn’t mean they’re risk-free. Ginseng can cause insomnia, may worsen autoimmune conditions, and could interfere with blood-clotting medications like warfarin. It may also lower blood sugar, which matters if you have diabetes or take blood sugar-lowering medication. Some evidence suggests ginseng is unsafe during pregnancy. Short-term use (up to six months) at recommended doses appears safe for most adults, but long-term safety data is limited.
Herbs with phytoestrogenic activity, like shatavari and fenugreek, deserve caution if you have a history of hormone-sensitive conditions such as estrogen receptor-positive breast cancer or endometriosis. These compounds bind to estrogen receptors by design, which is helpful for menopausal symptoms but potentially problematic when estrogen stimulation is medically undesirable. If you take prescription medications, particularly blood thinners, blood pressure drugs, antidepressants, or diabetes medications, checking for interactions with a pharmacist before adding any herbal supplement is a practical step worth taking.
