Bach thought of illness as the result of "a contradiction between the purposes of the soul and the personality's point of view." This internal war, according to Bach, leads to negative moods and energy blocking, which causes a lack of "harmony," thus leading to physical diseases.
Rather than being based on research using the scientific method, Bach's flower remedies were intuitively derived[8] and based on his perceived psychic connections to the plants.[9]p.185 If Bach felt a negative emotion, he would hold his hand over different plants, and if one alleviated the emotion, he would ascribe the power to heal that emotional problem to that plant. He believed that early morning sunlight passing through dew-drops on flower petals transferred the healing power of the flower onto the water,[10] so he would collect the dew drops from the plants and preserve the dew with an equal amount of brandy to produce a mother tincture which would be further diluted before use.[11] Later, he found that the amount of dew he could collect was not sufficient, so he would suspend flowers in spring water and allow the sun's rays to pass through them.[10]
Bach advertised his remedies in two daily newspapers, but since his practices did not follow any scientific protocol, and his methods and claims were unproven, the General Medical Council disapproved of his advertising. For example, in his treatise Heal Thyself he wrote:
“ Disease will never be cured or eradicated by present materialistic methods, for the simple reason that disease in its origin is not material . . . Disease is in essence the result of conflict between the Soul and Mind and will never be eradicated except by spiritual and mental effort. ”
