Erectile dysfunction (ED) is a condition that affects the ability to get or maintain an erection. Some people may prefer to use natural or herbal remedies to treat ED, but the evidence for their effectiveness and safety is limited. Here are some of the herbal remedies that may help treat ED, according to the available research:

• Ginseng: A popular herb that may improve blood flow, reduce stress, and enhance sexual function. However, the quality of the studies is low, and more research is needed to confirm the benefits and risks of ginseng for ED. ^{2 1}
• L-arginine: An amino acid that may help relax blood vessels and increase blood flow to the penis. However, the dose, duration, and safety of L-arginine for ED are unclear, and more studies are needed to establish its optimal use. ²
• Yohimbe: An extract from the bark of an African tree that may stimulate blood flow and nerves to the penis. However, it may also cause serious side effects, such as high blood pressure, rapid heart rate, anxiety, and insomnia. Therefore, it should be used with caution and under medical supervision. ^{2 1}
• Horny goat weed: A herb that may contain a compound that inhibits an enzyme that affects blood flow to the penis. However, there is no evidence that horny goat weed works for humans, and it may have side effects, such as dry mouth, nausea, and dizziness. ^{2 1}
• Ginkgo biloba: A herb that may improve blood circulation and relax blood vessels. However, the study was small and had methodological flaws. More research is needed to confirm the efficacy and safety of ginkgo biloba for ED. ^{2 1}
