Earth Kids TV Blog - So What? Herbs as Medicine

Herbs as Medicine

Herbs have been used as medicine for centuries. Plants have a long and rich history of medicinal use and, even in the era of modern medicine, their medicinal properties are still sought after. Most of today’s medicines come from nature but herbs are still some of the strongest and most effective sources of medicine around.

Medicinal Plant Research focuses on the propagation, cultivation and processing of South African medicinal plants, especially those species that are highly utilised. Many of these medicinal plants including the endemic species are often harvested unsustainably from their natural population. As a result, some species are becoming rare or threatened with extinction. The development of optimised propagation and cultivation technologies for medicinal plants is an intervention that can ensure a sustainable supply of good quality plant material for the growing medicinal plant-based industries, contribute towards the conservation of our natural resources and create job opportunities.

South Africa has a rich heritage of traditional herbal remedies and the country is blessed with an abundance of indigenous plants known for their healing properties. A large portion of the country falls into the Cape Floral Kingdom, containing approximately 4% of all the world’s plant species. Of these plants, 70% are endemic, meaning that they don’t occur naturally anywhere else in the world. With nearly 9,000 plant species found naturally in this area, it’s no surprise that many of South Africa’s traditional remedies are based on the curative properties of plants.

Aloe Vera

Aloe vera is a succulent plant species of the genus Aloe. It is an evergreen perennial which comes from the Arabian Peninsula.
