Medicinal plants nowadays

Humans have experimented with medicinal plants since ancient times, the oldest written evidence is said to date back 5000 years, found on a Sumerian slab from Nagpur containing 12 recipes for the preparation of natural remedies.

In the beginning, neither the use nor the consequences of the use of different medicinal plants were known, and it was through many trials and errors that mankind found the cures to the multiple diseases. Today, although we have built on previous discoveries, these cures are the result of meticulous scientific studies to obtain medicines of high safety and quality.

What are medicinal plants?

As the name suggests, medicinal plants are those that have the ability to cure an illness, whether physical (such as stomach pain) or mental (such as relieving stress or anxiety). These plants contain chemical substances in some part of them (root, stem, leaves or flowers) called active ingredients, which are obtained through a series of transformation processes and consist of a large number of benefits.

Some active ingredients are essential and volatile oils, which have anti-inflammatory, antiseptic, regenerative, etc. properties. Then there are organic acids, which act as analgesics; alkaloids, which facilitate the functioning of our organism; starch, which provides energy and is another anti-inflammatory; and many others such as minerals, sugars and vitamins.

There are different ways to prepare the active ingredients for consumption or application:

  • Infusions: The healing part is dissolved in hot water for better digestion.
  • Washes: Instead of drinking the infusions, they are used to treat external conditions, such as wounds or ulcers.
  • Salads: This is another way of ingesting the active ingredients, but in solid form.
  • Poultices: The beneficial part of the plant is crushed and then applied to the affected area.
  • Vapors: By subjecting certain plants to heat, they produce a vapor that is used to treat respiratory diseases.
  • Syrups: The active components are extracted with water and dissolved in honey or sugar.

Why are they important?

A large number of drugs are based on medicinal plants. For example, the common aspirin is made from acetylsalicylic acid, which comes from the bark of the white willow tree, and many sleeping pills are made from valerian. We say then that their importance comes from the fact that these remedies are the basis of our modern medicine and without them we would not have evolved in the same way.

Their importance and presence is such that the WHO is in charge of their continuous study, both to find out more applications of these plants and to disseminate the knowledge acquired about them.

A couple of decades ago the use of these plants increased in excess and got out of control, with cases of harmful effects on patients coming to light. However, it was not the fault of the remedies themselves, but of their misuse and poor quality. Therefore, this organization was asked to create a set of guidelines comprising a series of techniques and measures necessary for the proper cultivation and harvesting of medicinal plants.
