Leaves, roots, flowers, and bark are used in infusions, oils, ointments, or extracts to take advantage of their properties. Today, the use of medicinal plants has experienced a resurgence thanks to the interest in more natural and sustainable alternatives. Many of these plants are also used in the pharmaceutical industry to produce medicines and supplements, combining traditional knowledge with scientific research. Some, such as chamomile for digestion, valerian for relaxation, or arnica for reducing inflammation, have a long history of use and studies that support them. Although they are natural, their use requires knowledge, and always under the supervision of a healthcare professional. Self-medication should be avoided and keep in mind that natural is not always synonymous with sure.
