Herbal medicine can help to treat almost anything, as treatment is focussed on the person rather than on the illness. Instead of targeting specific diseases, herbs work by supporting a person’s physiology and promoting self-healing mechanisms. Here are some of the ways herbs can help. 

In holistic medicine, disorders of the skin are seen as manifestations of something deeper going on within the body. This may be related to digestion, stress, diabetes, autoimmune disease, or a combination of things.

Herbs have been shown to stimulate various nervous system chemicals, such as serotonin, adrenaline or dopamine. However, holistic medicine considers the nervous system from a wider perspective.

In holistic medicine, the gut is the seat of human health. Like any complex system of nature, the gut has an innate ability to self-correct after periods of dysfunction, which is why herbs are so well suited to digestive problems.

The female reproductive system depends on a constant cascade of finely tuned hormones. Herbal medicine subtly ‘nudges’ physiology back into order, especially where symptoms do not fall into a single specific diagnosis.

Three of Europe’s best selling herbal products, Ginkgo, garlic and hawthorn, are traditional remedies highly adapted to suit the modern prevalence of heart & circulatory disease. But herbs have a lot more to offer.

In holistic medicine, the respiratory system is seen as an extension of the digestive system, and therefore equally susceptible to diet, lifestyle habits and environmental changes. Herbs are also powerful anti-infectious agents.

Herbs called 'adaptogens' are known to to increase the body’s resilience to stress by initiating small stress-mimicking effects in the body, called ‘hormesis’, thereby improving endocrine, immune and metabolic function.

With stress and poor diet being the main contributors to chronic inflammation in the body, it is not surprising that conditions like arthritis and psoriasis are increasingly becoming an issue that conventional medicine finds difficult to resolve.

Is there any evidence for how herbal medicines work? 

Studies called 'systematic reviews' are considered the gold standard of medical research - they are essentially summaries of all the available research on specific treatments, and their conclusions dictate the practice of modern 'evidence-based medicine'. However, some studies done on herbs, especially older studies, just don't meet the strict inclusion criteria for these literature reviews. 

A big problem with getting high quality evidence for herbal medicine is that some herbs have very distinct tastes (like chilli, ginger or mint) so it is difficult to create a convincing placebo. Another problem is the limited funding available for testing plant extracts that cannot be patented into a sellable drug.

Herbs vary in their composition according to where they are grown, how and when they are picked, dried, stored etc, which causes variations in results from different studies. And, crucially, different people with the same condition tend to respond completely differently to the same herbal treatment.

It is often said in the media that there is ‘no evidence’ for herbal medicines. What this often means is that there is a lack of high quality evidence that meets all the requirements - requirements that have been set with pharmaceutical drugs in mind, not complex, living medicines like plants. It also means that there is no evidence that they don’t work, either.


In addition to the limited scientific evidence available for the use of certain herbs, medical herbalists have the advantage of being able to draw on the wisdom that has been passed down through generations of plant healers, as well as their own clinical experience, to make judgements about whether or not a plant will work for a specific condition or patient. 


How do herbs work, compared to pharmaceutical drugs?

Conventional medicines use single 'active ingredients', often extracted from plants, like aspirin from willow bark and morphine from opium poppies. Active ingredients are much stronger and more direct than the whole plant, and therefore often involve side effects.

It is easier for organisms like bacteria to develop resistance to single-ingredient drugs like antibiotics, by evolving mechanisms that help it survive - this doesn't tend to happen with plant medicines. 

People also become used to certain drugs after they've been taking them for along time, like blood pressure medication, and need a stronger dose to produce the same effects. 

In herbal medicines, because there are so many ingredients in a whole plant extract, these problems generally do not exist. In the herbalists’ view, the complex nature of the herbal prescription is perfectly suited to the complex nature of an individuals’ condition, especially where a more gentle but long-term remedy is needed. This doesn't mean that all herbs are softies – some are very powerful and the dosage of each is incredibly important.

However, the hugely diverse chemical composition of herbal medicines means it is very difficult to try and separate all the compounds from each other to find out exactly what effect they are having. That is another reason why there is a lot less evidence for herbs, and a lot more evidence for conventional medicines.


Can herbs be used alongside my current medication?

Yes, most of the time. There are only a few examples where this is not a good idea: St John's Wort, for example, speeds up the metabolism of certain drugs like the Pill, warfarin and statins.

A herbalist will always check that what they want to prescribe you fits in with the medicines you're taking so that no adverse reactions happen.

Some types of herbal or natural treatment options can even protect against the side effects of conventional medication. Turmeric has been shown to be beneficial in lessening the side effect of oral mucositis after head and neck radiotherapy.


There is also high quality evidence to suggest that probiotics are essential in replacing the body's stores of healthy gut bacteria after a undergoing a course of antibiotics.


How long before I start noticing the effects of my herbal prescription?

The time it takes to treat successfully with herbs will vary according to each individual person - the longer you've had the condition, the longer it will take to treat.

For example, a simple case of anxiety can often be resolved within less than one month of treatment, whereas a complex picture of high blood pressure or diabetes can take a lot longer may require a long-term maintenance dose.

In general, 3 months is a good time frame to bear in mind. If you haven't experienced a change within 3 months, a different prescription or approach to treatment is needed.
