Aromatherapy has short-term ‘de-stressing’ effects which can contribute to enhanced wellbeing after treatment. There is no evidence that aromatherapy can treat specific diseases.
Ayurvedic Tradition
Background
Ayurveda has been used in India for roughly 5,000 years. It includes individualized herbal remedies, diet, exercise (yoga), spiritual approaches like meditation, massage and other interventions. Health is perceived as a balance of physical, emotional and spiritual energies, and any deviation from health is thought to be caused by an imbalance of these elements. Treatment is aimed at re-establishing the balance through individualized prescriptions, usually of several interventions simultaneously.
Ayurvedic practitioners will take a medical history, examine the patient, diagnose the nature of the imbalance and try to restore balance through their prescriptions. There is much emphasis on lifestyle advice, but Ayurvedic medicine supplements are also prescribed frequently. A consultation might take 30–60 minutes and numerous sessions are usually recommended, often lasting up to a year. All conditions are claimed to be treatable in the Ayurvedic tradition.
What is the evidence?
The whole system of Ayurveda has not been submitted to clinical trials, but elements of it have. The results are mixed. For instance, yoga has proven benefits for cardiovascular health. A recent trial of Indian massage, however, showed no positive effects in stroke patients. Ayurvedic remedies usually contain a multitude of herbal and other compounds. Some encouraging findings exist for conditions like acne, constipation, diabetes, chronic heart failure, obesity and rheumatoid arthritis. However, in none of these cases is the evidence sufficiently strong to warrant a positive recommendation. (The evidence for specific herbal remedies is discussed in Chapter 5.)
Ayurdevic medicines have regularly been implicated for containing substances such as heavy metals. These can either be a contaminant or a deliberate addition — according to Ayurvedic belief, they generate positive medicinal effects if handled properly. In reality, however, heavy metals are highly toxic no matter how they are prepared.
Conclusion
Ayurdevic healthcare is a complex system that cannot be easily evaluated. The current evidence suggests that some of its elements are effective while many others are essentially untested, or overtly dangerous, e.g. many herbal preparations.
Bach Flower Remedies
Background
The concept was developed by Edward Bach, who had worked as a micro biologist at the Royal London Homoeopathic Hospital in the early twentieth century. Inspired by the principles of homeopathy, Bach identified thirty-eight flower remedies, each one corresponding to an emotional disturbance such as depression, fear, loneliness or oversensitivity. Administering the correct remedy, he believed, would cure the emotional disturbance and consequently the physical or psychological illness. For example, heather is used to treat self-centredness and honeysuckle is an antidote for those who live in the past. Similarly, wild rose is supposedly helpful in cases of apathy, and vervain treats the opposite problem of over-enthusiasm.
Flower remedies (‘Bach Flower Remedies’ is a brand name) are produced by placing the fresh flowers into spring water. Subsequently brandy is added to make up the actual remedies, which are similar to homeopathic remedies in that both are usually so dilute that no pharmacological action is conceivable. Also both schools claim to work through some sort of ‘energy’ transfer. However, homeopaths are adamant that flower remedies are fundamentally different: succussion (or shaking) is not part of the process of making flower remedies, and their prescription does not follow the ‘like cures like’ principle.
Flower remedies can be bought over the counter, but proponents argue it is best to consult a trained therapist. The therapist would identify the patient’s underlying emotional imbalance, which, in turn, determines the choice of remedy. Flower remedies are also often recommended to healthy individuals with a view to preventing illness.
