I am no youngster by any stretch of the imagination. I do exercise regularly. mostly cals, swimming, stretching. Always preferred natural ways.
Chinese herbs for male fertility are a huge part of the ancient science. They are specifically designed to keep the male reproductive system very strong and able to perform into advanced years. Stories of men fathering children in their 80's and beyond. Usually best prescribed after a pulse reading and tongue exam but if you are otherwise healthy, you can just use the highly touted herbs for male libido.
In Chinese medicine, herbs are usually never taken alone. usually in combination. Some herbs are so strong, there are precautions. Now a days even Chinese herbs are in extracted and concentrated forms. they are strong but drug-like in effects. (long-winded, sorry, I know)
BUT go to any Chinese herbal store. I counted 13 once in the walking distance around Main Street Flushing. Ask for a bag of Yin Yang Huo -- about 5 bucks or so for a pound. That will last a long time. Don't boil the whole pound. take a good handful. sorry I can't be more specific. they used to sell them in neat stacks of leaves packed like playing cards and I used about a quarter inch. Really enough!!!! In the States now when I am there, I noticed that they come from China now like a big bag of leaves not neatly stacked . so it is harder to estimate.
anyway, the meaning of Yin Yang Huo is Horny Goat Weed and I can vouch for it. it is also known in Latin as Herba Epimedium. I once went to an herbalist for a bad back and got a consistent formula that relaxed my back. On a later visit, the herbalist included Yin Yang Huo which is also a kidney strengthener. In the middle of the night I rose up crazed with desire. I asked the herbalist what change did he make in the formula and he told me Yin Yang Huo. Its effects can be very very powerful. I am afraid of the extract. I put it on the shelf. (I never used Viagra or Cialis but the extract was really intense.) but the leaves promote testosterone. After 24 hours you feel very potent. You can take a good bunch of it and boil it in say 2 quarts of water, bring it to a boil and then low heat covered for about 1 hour until you have about a quart. then drink 3/4 cup at night and in the morning. You can add some goji berries (small handful) and Chinese red dates (about 7) maybe a piece of shu di huang a cut up piece of fresh ginger (about 2 fingers) or if you are not into Chinese herbs too much, just a handful of good quality raisins.
Look, I know there was a time in our lives when all we needed was a slice of pizza for an aphrodisiac for libido but even the ancients realized that time degenerates our bodies and when that happens it was time for spiritual pursuits. But if you want to hang on to these wonderful experiences, fine. so the ancients devised formulas especially for kings with harems to keep the Old Boy strong and in command.
You know, everything has side-effects -- EVERYTHING. Even natural food in excess, not to mention junk food.
So, the only reason I make this suggestion is that natural leaves and fruits boiled in an herbal soup have far less side effects than drugs, pills, extracts, injections. In the herbal world there are so many ways to go. You can find others to suit you better or in combination.
but yin yang huo is really cheap and highly common. you could easily grow it in your back yard and then dry the leaves in your attic.
also be careful with any sexual stimulants as they could enlarge the prostate gland as it is filled with sexual fluids as a result of the increased production of testosterone.
Listen, boys of all ages, be strong always and be safe always. Your life and your health are a great and powerful gift from nature. Take a rest sometimes to replenish so you are double strong on your next outing. Remember, there is always tomorrow and next week and next year. You want and need health, good sexual stamina and longevity.
