In modern times, traditional botanical remedies have been largely forgotten in the Western world. Or at, the very least, they're considered to be inferior to synthetic drugs manufactured by pharmaceutical companies. People are naive enough to believe these drugs are modern inventions that some scientistic conjured up in a lab somewhere. While that might be the case for a few synthetic drugs, most remedies are derived from natural compounds found in plants, algae, and even insects.
In fact, even though synthetic drugs might be stronger and better standardized, plant-based remedies still make fabulous treatments. In Asia, herbal pharmacies are still widespread and offer natural treatments for all health issues from heart disease to erectile dysfunction, and many more.
Since plant compounds cannot be patented directly—as they are an "invention" of nature, not humans—nobody wants to invest too much money in studying them in detail. After all, you can't brand and sell chamomile or cayenne pepper. What happens instead is that scientists find an aspect of a plant chemical that seems interesting, then modify the molecule in a way that would give birth to a unique compound with similar (and hopefully better) effects. A compound that can be patented and sold all around.
Unfortunately, the results are often the opposite. While the new compound might prove to be effective, it likely would now come with many more side effects than the original one had. There is, indeed, a certain plant wisdom that scientists have yet to grasp.
An example of this is the adaptogenic class of herbs such as ginseng, rhodiola, and schisandra. They can all have a stimulating or sedative effect on the human nervous system depending on the needs of the body. For example, it will be soothing if you're stressed, but stimulating if you're tired. What's also great is that they're practically free from side effects and completely non-toxic.
This effect is basically unheard of in conventional Western medicine, as all our drugs tend to work in a more "dirty" way: always one-directional and often full of potential side effects. And still, modern medicine looks down on natural therapies such as plants. Moreover, if you bring it up with your doctor the answer is often that there is no evidence to support their use. Well, in all honesty, that's simply because most of the world revolves around money and many doctors forget (or aren't aware) that the Chinese have used plant-based drugs as their primary form of treatment for many thousands of years and up until modern times.
No matter if you believe in the power of plants or not, it cannot be denied that they can be effective non-toxic remedies for men’s health issues.
