Herbal Medicine

Herbs contain a large number of naturally occurring chemicals (constituents) that have some type of biological activity. Herbs work in a similar fashion to many pharmaceutical preparations. In fact, some pharmaceutical medicines are still obtained from plants. Western herbalists believe that herbs should be used in their complete form to ensure the balance of constituents contained in the plant is utilised. They consider that herbal remedies are of most benefit when used to treat chronic, ongoing conditions. There are generally no quick-fix herbal treatments. Herbalists also believe that herbs can be very effective in the treatment of many conditions, but without the unwanted side effects that are often seen in conventional pharmaceutical treatments. 

Herbal medicine offers treatments for virtually every ailment affecting any body system. Common conditions that can be treated include: 

• Psoriasis, acne and eczema. 
• Digestive problems such as peptic ulcer, colitis, irritable bowel syndrome and indigestion and heartburn.
• Heart and circulatory conditions such as angina, high blood pressure, varicose veins and ulcers.
• Gynaecological disorders such as premenstrual syndrome and menopausal problems.
• Arthritis.
• Insomnia and sleep issues.
• Stress and nervous related conditions.
• Headaches and migraines.
• Upper respiratory tract infections.
• Colds and flu.
• Allergic responses such as hay fever and asthma. 

Note that when you see a herbalist you should always tell them what conventional medicines you are taking. You should also tell your doctor if you are planning to start a course of herbal medicine. You should never stop taking your conventional medicines in favour of herbs unless your doctor knows and approves.

Herbs can be very potent and, if used incorrectly, can cause serious adverse effects. Also some herbs can affect how your body responds to prescription and over-the-counter medicines, either decreasing or increasing the effects of these medicines. For example, St John’s wort can interfere with birth control pills, and gingko biloba can increase your risk of bleeding with anticoagulant (blood-thinning) medicines. Always consult your medical practitioner before consuming herbal medicines. 

Medicinal products containing herbs are regulated in Australia by the Therapeutic Goods Administration. If the ingredients are deemed to be higher risk, whether because of their toxicity, likely length of use, side effects, interactions or other feature, the medicine will have to be a “registered” medicine with the designation ‘AUST R’ on the label. If it is deemed low risk, the product can be labelled a “listed medicine” with the label designation ‘AUST L’. The indications and claims made for listed medicines are not investigated or evaluated before the medicines are marketed, but the manufacturers are required to hold evidence to support any claims they make. On the other hand, registered complementary medicines are assessed individually for quality, safety and efficacy.
