Medicinal herbs are plants which contain chemicals that have an effect upon the body, but how useful are these herbs?
Some people swear by them, yet others are highly suspicious.
If you delve a little deeper, you'll soon discover that many of the medicines prescribed by doctors and sold by pharmacists originate from herbs. For instance, did you know that Aspirin is derived from salicin which is found in willow bark? Although the proper processing of herbs for medicinal purposes is complex, and beyond the skills of the average home gardener, there are many herbs which are relatively easy to grow and safe for most people to use. We're talking here about things like Rosemary, Lavender, Garlic and Lemon Balm. Many of them also have the added benefit of attracting predatory insects to your garden which will keep unwanted pests in check.

How Do Herbs Affect the Body?
The effect of medicinal herbs on our bodies may be mild or strong. For internal preparations, to some extent this depends upon the person. A small child, sick adult, or a frail elderly person would require a lower dosage than a healthy adult. The effect of herbs can also be influenced by a number of other factors:
The species and variety of plant - there can be subtle but important differences between two plants which may appear to be identical. For example, many herbs now sold are cultivated varieties of the original species and may not have the chemical constituents of the species form.
- How it was grown - herbs that are over-fertilised and watered tend to have a lower concentration of the important chemical constituents.
- The parts of the plant used - the chemical may only be found in certain plant parts such as root, leaf, stem, flower, or fruit.
- Mature or new growth - the chemical may be stronger in mature plant parts.
- Harvest time - time of day, time of year, weather conditions at the time, etc.
- The preparation of the medicine - as an oil, tablet, tea, ointment, and so on.
- The storage of the medicine - some medicines store well, but generally fresh is best.
- How it is used - some herbs may be safe to use externally, but the same herb may cause serious health problems if taken internally.
- Concentration level - some may be beneficial in a certain concentration, but dangerous in another concentration.
How are Medicinal Herbs Used?
Herbal Medicine - herbal products tend to work with the body's natural processes to combat disease (rather than by blocking natural processes as in conventional allopathic medicine). In extreme situations, herbal medicine may be inappropriate.
Naturopathy - this is based on helping the body heal itself by attending to the five "cornerstones" of good health: good nutrition, a good (psychological) attitude, fresh air, exercise, and sunshine. Disease is seen as a body reacting against a build-up of toxins. Herbs may be used to stimulate faster elimination of these toxins from the body.
Aromatherapy - scented oils derived from herbs are used to treat various ailments from mild stress or headaches, to more severe problems. This might involve massage with scented oils, washing with scented soaps and taking scented baths, or scenting the air with fragrant candles, atomisers, or potpourri.
Homoeopathy - this is based on a principle that "like cures like" (similar to the concept of immunisation). The body is seen to have a self-healing potential, so by taking a very dilute solution of something (normally derived from herbs), which will cause the same symptoms as an illness, the body is then stimulated to combat those symptoms, and in doing so, combat the illness.
What do our Students Say?
I have never found the staff at any other learning institution as supportive as the staff at ACS. This gives one a lot of peace of mind and confidence to go on - at every squeak from my side, you guys have always been there, immediately to sort me out. The feedback on my lessons has always been really good and meaningful and an important source of my learning. Thanks!...
Student with ACS
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.
