ACS Student comment: "The Medicinal Herbs course has been an invaluable experience and reference towards doing Naturopathy at University. The tutors are very approachable and informed, the course structure is very well laid out and the enclosed texts and information will be a very useful reference in years to come. Without going to University these courses, in particular Medicinal Herbs, are some of the only other quality information that one can receive at a very reasonable price and a very flexible study structure." Matthew, Medicinal Herbs

SCOPE AND POTENTIAL IS LARGELY UNTAPPED

Medicinal herbs are plants which contain chemicals that have a healing effect on the human body.

The potential is huge, but our knowledge of the bioactive constituents of plants is limited. A relatively small proportion of plants are known well, but most hold secrets that are largely still to be discovered. In fact there are still many plants to be discovered too; there is believed to be thousands of medicinal plant species growing in the rainforests of the world.

Scientists working in the jungles of South America are uncovering previously unknown species regularly many of which are thought to have medicinal qualities. These plants may hold the key to cures for many serious ailments and diseases.

Hundreds of thousands of different plants are cultivated in our gardens; and more than half of those species are known to contain chemicals that affect the human body. Many are toxic. Some can be ingested in small but not large quantities. Others are thought to be perfectly safe.

Pharmaceuticals that are used in modern medicine include drugs that are derived from medicinal plants. Medical research that is undertaken will often be based upon extracts from medicinal herbs.
