[13][14] As a practicing homeopathic doctor she was interviewed by journalists Christian Weymayr and Nicole Heißmann for their book The Homeopathy Lie (German title: Die Homöopathie-Lüge).
[20] She described the beginning of her doubts about homeopathy as coming "…when [she] learned that, in evaluating the efficacy of a therapy, the decisive thing is not one's experience but rather the results of clinical studies.
[22][23] At the end of this learning process, Grams decided to abandon her own private homeopathic practice, and livelihood, because she no longer wanted to offer therapies that she could not fully stand behind.
[14] In explaining this decision, she draws a contrast between the lack of scientific support[17][24][25] for homeopathy and the positive secondary effects of the homeopathic setting, including the approachable and attentive style of patient care sometimes termed talking medicine.
[26] Grams describes Samuel Hahnemann, the German originator of homeopathy, as a clever person who rebelled against a superstitious, prescientific medical establishment which promoted therapies that imperiled the lives of patients; as she put it, "[h]omeopathy was, at the time, the lesser evil.
"[30] Although Grams fundamentally opposes homeopathy as a discipline, she wishes to see mainstream health systems embrace the idea of better medicine – an effort to enable intensive attention to the patient in daily medical practice.
She nonetheless considers the practical element of homeopathy – attentiveness to the patient – valuable, opining that physicians "must carry this over into everyday medical and clinical life – but without the magic part involving succussion and potentization.
"[34] In an interview with Der Spiegel, Grams said that given the lack of evidence for homeopathic medicines' efficacy exceeding the placebo effect, "[i]f a group of doctors staunchly asserts that homeopathy works, one must – for the sake of patients – object.
"[35] The impact of Grams' position in print media,[36][37][16][38][39][40][34][41] radio, and television[42][43][44][45] was an essential factor in the intensified German public discourse surrounding homeopathy since 2015.
[54] She lent her expertise as a member of the "Münsteraner Kreis", a free association of scientists on the subject of "Pseudomedicine in Public Health", as an author in support of the Münster Memorandum on Practitioners of Alternative Medicine, which aims to mitigate the potential for patient harm from therapists who lack academic medical education (Heilpraktiker – literally healing practitioners) by proposing a German regulatory framework to balance the concerns of patient autonomy and freedom of therapy against fairness to health insurance providers and insurees.
Homeopaths who reviewed her first book didn't go to a factual discourse but have questioned the motivation behind her conversion (i.e., her change of mind based on rational arguments), mostly in a defamatory way.
She hopes to reach people who share the false popular perception of homeopathic therapy as "gentle", "empathetic" and basically the "better medicine" and prompt them to re-examine that opinion on a factual basis.
