Medicinal plants most interesting for science

We live in the XXI century tied to many medicines and products to combat diseases, when several centuries ago it was said that food was true health.

Therefore, the scientific community has been looking for healthy alternatives to the main diseases of this century, such as heart attacks, diabetes, obesity and cancer, for many years.

From the scientific point of view, we wanted to look for 9 medicinal plants and seeds that offer multiple advantages for our body.

Currently, between 10 and 15% of all medicines considered essential by the World Health Organization contain plant extracts. However, this dynamic is changing and these active materials are increasingly used.

In turn, we must also take into account the side effects of all this type of medicinal plants, cases of allergies, stomach problems and abuses of the phytoactive compounds present.

We have gathered 9 products with clinical trials that have endorsed their medicinal properties, which are increasingly used as a preventive and reinforcement of food.

Finally, keep in mind that not all medicinal plants are endorsed or registered by the Food and Drug Administration, so ultimately you have to consult with the medical specialist or consult the registered technical information.

Therefore, we wanted to reflect the current safety of the different plants and seeds under a classification level, as well as the tests or medical trials carried out, on a scale ranging from 0 (without trials) to 5 (with a lot of medical and clinical support).

  • Safety: 4/5

Turmeric is currently living a time of splendor due to recent research about its potential in medicine.

The potential medicinal effects of turmeric are due, in general, to the content of curcumin, a natural dye and a polyphenol.

In addition, it contains other interesting substances for modern medicine:

  • Prolonged use in high amounts can lead to side effects linked to stomach problems.
  • The assimilation rate of turmeric is very low, which is why it is sometimes successfully combines with piperine.
