Alternative medications refer to treatments used in place of conventional (mainstream) medicine. One common example is herbal supplements. For instance, Echinacea is a popular herbal remedy often taken to help prevent or treat the common cold. Other examples include acupuncture, homeopathy, and the use of dietary supplements such as St. John's Wort for mild depression.
It's important to consult healthcare professionals before starting any alternative medication, as some may interact with conventional treatments or have side effects.
