No, I was intending to do exactly the opposite. Sorry that that was unclear. My only point was that the cure is entirely a mental one, not that the suffering is fake. I suspect that you can develop symptoms by being around other people who have the symptoms. That doesn't mean your experiences aren't legitimate. As I said in the comment, I myself have had this experience. In my case it started with imagining things about my past experiences, but quickly turned into a real ordeal for me.

I agree, and we've tried to help her. She unfortunately has a pretty strong skepticism of traditional medicine and has an extremely unhealthy lifestyle that could more than explain most of her symptoms, but has chosen to micro-focus on the things people on her Facebook feed tell her are her problems. So she says, for example, that she has pain in her gut and gets headaches whenever she eats gluten. This is something she'd never complained of before, and a test for celiac disease turned up nothing. But still she insists. My only explanation is not that she's pretending to suffer, but rather that she's created the gluten intolerance herself. That it's a mental problem. Next time I visit, she'll probably be back to eating bread again, this time totally convinced something else is going on.

I'd ask you to consider that perhaps your sources of information, all apparently non-scientific (and many also having financial interests in "all natural" products) may not be the best counter-point to mainstream scientific research.
Here are some quotes:
Synthetic musks used in fragrances are of particular concern from an ecological perspective. Several of musk compounds are persistent in the environment and build up (bioaccumulate) in the fatty tissue of aquatic organisms.
diethyl phthalate, or DEP, is widely used in cosmetic fragrances to make the scent linger. Phthalates are choice ingredients in cosmetics because they are cheap and versatile. However, the European Commission on Endocrine Disruption has listed DEP as a Category 1 priority substance, based on evidence that it interferes with hormone function. Phthalates have been linked to early puberty in girls, reduced sperm count in men, and reproductive defects in the developing male fetus (when the mother is exposed during pregnancy).
That sounds pretty science-y to me, admittedly a layperson.
Your comment seems to imply that psycho-somatic symptoms are not real symptoms and people who suffer from them are behaving irrationally. If so, you are incorrect.
Psycho-somatic symptoms are real measurable physical problems in the body that are triggered by the brain. They are not imagined problems. For example, my perfume sensitivity triggered real nasal congestion. You could hook up a nasal flow meter and record data showing that my nostrils were blocked. For people with chronic lower back pain, you could connect a sensor to the pain nerves and measure the pain signals going from the lower back muscles into the spinal column.
Suffering from a psycho-somatic disorder does not imply that the person is rational or irrational. Psycho-somatic problems arise from everyday life situations. For example, my own perfume sensitivity developed over a year of high pressure at the office. My desk was near the women's restroom. Several times an hour, people wearing perfume would walk by my desk to use the restroom, and then walk by again a few minutes later. I became distracted when I smelled their perfume. I would respond to the distraction by desperately forcing myself to concentrate. When concentrating was difficult, I felt more stress. Gradually, my brain developed an automatic response: smell perfume -> feel anxiety and stress. Unfortunately, this was a self-reinforcing habit. After I recognized the root cause, I was able to un-learn the emotional habit and cure the psycho-somatic disorder.
Your tone implies that people develop psycho-somatic disorders after "falling for" some false idea. That is incorrect. Some would consider it extremely condescending and would take offense. When a person suffers from excruciating lower back pain, they are not "falling for" the idea that they have a back injury. They are just suffering. They try to understand why they are suffering. "I have a bad back" is a reasonable explanation. The knowledge of the most common cause of lower back pain is not yet widespread: that lower back pain is usually caused by subconscious tensing of muscles. Please re-examine your bias about psycho-somatic disorders. They are real symptoms suffered by rational people.
I assure you that your mother is suffering real symptoms. They are very likely not psycho-somatic. I commend her relentless search for root cause and cure. You could help her: Take her to consult with experts, help her objectively record her symptoms, help her systematically test different hypotheses and interventions, find a fun fitness class and attend it with her, research healthy recipes and cook them together, and make sure she takes enough vitamin D3. My own mother developed cancer and there was little I could do to help her.
