Herbal remedies, also known as botanical medicine, have been used in many traditional medicine systems. They are produced from all parts of a plant including the roots, leaves, berries, and flowers. These may contain active ingredients that can cause chemical changes in the body. Herbal remedies can be taken by mouth or applied to the skin to treat disease and promote health. Sometimes herbs and plants are categorized as biological treatments.

Marijuana - Types, Uses & Adverse effects

Medical use of cannabis

Marijuana is a drug that comes from the cannabis plant. The main psychoactive ingredient in marijuana is THC (delta-9-tetrahydrocannabinol). THC is a type of cannabinoid. There are many other types of cannabinoids in marijuana. Cannabinoids are chemicals that act on certain receptors on cells in our body, especially cells in the central nervous system.

Recent changes in Commonwealth and state laws mean that medicinal cannabis products can now be used in Australia to assist in the treatment and management of cancer-related symptoms and side effects.

Medicinal cannabis may be prescribed to people with cancer to stimulate appetite or weight gain, or to manage nausea, vomiting, or pain. Currently, there is no evidence to suggest that medicinal cannabis is effective in the treatment or management of cancer itself. It is therefore used in symptom management only.

If you are interested in using medicinal cannabis to assist in relieving some of your cancer symptoms or cancer-related side effects, the first step is to talk to your doctor. Medicinal cannabis can only be accessed legally through your treating doctor and specialists. Your doctor can only prescribe medicinal cannabis if they believe it will be beneficial in the relief of your symptoms.

What is Western Herbal Medicine? - Ultra Health Therapies

Why use it

Herbal medicines are often used to help with the side effects of conventional cancer treatments, such as lowering fatigue and improving wellbeing. Evidence shows they should be used in addition to conventional therapies, rather than as an alternative.

What to expect

After taking a case history, the practitioner puts together a holistic picture of your health. They will look for underlying reasons for your ill health or symptoms, and dispense a remedy addressing the causes and symptoms of your illness. They may give you a pre-made herbal formula or make up a blend of herbs specifically for your needs. Herbal medicines can be prepared as liquid extracts taken with water or as a tea (infusion), or as creams or tablets.

The most well-known in Australia are the Original Bach Flower Remedies, developed in the 1930s in England, and Australian Bush Flower Essences, developed in Australia in the 1980s.

Flower remedies are used to balance the mind, body, and spirit, and help you cope with emotional problems, which can sometimes contribute to poor health.

What are Flower Essences? | AromaWeb

What to expect

Much like a counseling session, the therapist will ask questions and listen to you talk about yourself, the problems you are experiencing, and how you feel about or approach certain situations. This enables the therapist to prepare a remedy – usually a blend of essences – tailored specifically for you, which is taken in water several times a day.


Scientific evidence does not support the use of flower remedies for treating diseases. However, anecdotal evidence suggests they help reduce fear, anxiety, or depression.

Herbs and spices can do so much more than enhance the flavor of food. They can help stimulate the immune system and help prevent cancer.

Here are six ways to spice up your food and keep you in good health.

Know the exact amount of turmeric you should consume in a day - Times of India

Ginger: Health benefits and dietary tips

Saffron: Health benefits, side effects, and how to use it

4) Saffron: This spice may be the most expensive, but it packs a good punch. It contains crocins (water-soluble carotenoids) that may inhibit tumor growth and progression of cancer.

What Is Oregano? Tips for Growing and Using the Herb

5) Oregano: The richest source of antioxidants among herbs slows cancer growth and promotes apoptosis (cell death). It carries antibacterial properties and is a natural disinfectant.

Tip: Marinating with oregano can help reduce the formation of heterocyclic amines (HCAs) created when meat is cooked at high temperatures.

Garlic: Proven health benefits and uses

6) Garlic: The most powerful anti-cancer spice is part of the cancer-fighting allium group (onions, shallots, scallions, leeks, chives). Garlic helps boost the immune system to help fight diseases, as well as colds and flu. It also decreases the growth of cancer cells.

Tip: Take one daily dose – 1 clove and remember to “chop and stop” – chop and then let it sit for 10 minutes before using to allow for the formation of allicin (enzyme).
