After serious issues piling up for a very long time and an equally long journey to get to the root what was bothering me medically I presented to Dr. Douwes a couple years back in his clinic in Bad Aibling.
The experience was a bit frightening, to say the least. Their methodology to get a diagnosis was basically just examining my medical history followed by a dark field microscopy (i.e. visually checking a blood sample for spirochetes). After that I was diagnosed with late stage lyme and offered two options: a very handwritten prescription (pencil on notepad, w/o doctors signature, not rubberstamped, looking very shady) for herbal ingredients (basically artemisia annua leaves and some roots to brew a tea) - without any tips where to get that from and not really exact dosages given. Option 2: ambulant Hyperthermia + painkillers (to supress pain from the hyperthermia) + a combination of antibiotics (parenteral) for 2 or 3 weeks. Extracting a fortune (20k ballpark)
They also offer hyperthermia treatment for cancer and long covid & me/cfs if I am not mistaken.
The visit really had a smell to it and left me with unease. Look up the group's company network in the Handelsregister and decide for yourself, I got some PE vibes from it. I chickened out and went to someone else, luckily Germany has quite a few private MDs specializing on lyme and other tickborne diseases. What I got in general: most treatments are not evidence based and theres lots of snake oil around, some of the patients are very desparate, me included back then. PS: I made good progress, but am still on meds since. Apparently there's no eradication for late stage lyme. Maybe there are lucky cases, but the slow growth of borrelia spirochetes makes treatment very tedious, much like or even worse than with tuberculosis. I am sure that their treatment actually does help, but it is kind of a hail mary (combo of broad spectrum antibiotics is basically applying blunt force).
