Herbs are natures own pharmacy. Indiginous people are drawn to them instinctively for health regulation, as are animals. Notice how cats and dogs select certain grasses for themselves in times of need. Confidence in these wonderful health regulators amongst the general public has been undermined by the prolification of chemical drug therapy.

Nature v Science who's got it right?

Active ingredients or whole plants? The valuable and potent chemicals in plants are what pharmacists consider to be their active ingredients, and vast amounts of money go into the search for potential new ways to use these chemicals to make new drugs.
But the isolation and synthesis of specific active ingredients, such as aspirin from willow bark and digoxin from foxglove, is a mistake and may even be harmful.
In the plants themselves, these powerful constituents are balanced and made accessible to the body by the numerous other constituents present.

For example, the Chinese herb ma-huang (Ephedra sinica) contains an alkaloid called ephedrine, which, in addition to alleviating conditions such as asthma, raises blood pressure if given as an extract drug. However, the plant also contains six other alkaloids, one of which actually prevents a rise in blood pressure and an increase in heart rate. The isolated drug is dangerous, but the whole plant is balanced by nature to make a safer remedy. Why then don't the chemists extract all seven alkaloids? They clearly don't trust natures own skills in balancing herbal remedies.

These natural medicines tend to be used in conjunction with other therapies at the clinic, although it is common for us to treat illnesses, both physical and mental, using these modalities in their own right.
