Tongkat Ali (Eurycoma longiflora) (Figure 7): this native plant found through SE Asia is used as an Aphrodisiac since 1996 (5). It has to be used regularly and works by enhancing the testosterone and cGMP production. Benefits are felt gradually over a period of time, mainly because it enhances the natural biological synthesis of testosterone. When the level is increased, health and vitality are restored. In studies on Mice, Tongkat Ali increases the number of times and duration of sexual performance of the animals under study (8) with testosterone levels increasing up to 440% in some animals. In a recent study on humans, 62% of subjects showed an increase of the free testosterone index indicating it’s biostimulatory effect on steroidogenesis. It has also been shown to increase sperm concentration and motility and increases energy in the individual by enhancing ATP production by 60% thru oxidative phosphorylation.
Masturbating and watching porn cause negative impacts on both physical and mental health. These activities make too much sexual stimulation. Hence the brain will get overloaded.

Dr. Julian Nesbitt said: “Watching porn has a negative psychological effect as can make your expectation of sex unrealistic and therefore you are no longer aroused by your regular partner. Make sure your open with your partner about what turns you on to have a better overall sexual experience.”
Ginkgo biloba. Ginkgo is an herb that is used in Chinese medicine that’s thought to improve blood flow. "Any ED treatment that improves blood flow may help," explains Dr. Harris. "An erection is just blood in and blood out." However, the evidence that ginkgo can improve blood flow in ED is limited, and most experts say the jury is still out. In addition, ginkgo can increase the risk for bleeding problems if combined with certain medications, such as warfarin (Coumadin).
If you have symptoms of ED, it’s important to check with your doctor before trying any treatments on your own. This is because ED can be a sign of other health problems. For instance, heart disease or high cholesterol could cause ED symptoms. With a diagnosis, your doctor could recommend a number of steps that would likely improve both your heart health and your ED. These steps include lowering your cholesterol, reducing your weight, or taking medications to unclog your blood vessels.
