Just my two cents:
I feel like the text in this image probably overlaps enough with medical or scientific claims that sources probably ought to be provided. There are definitely remedies in nature, but the world is rife with people saying any number of things will fix your medical or mental health challenges, and when wrong or unsupported claims are shared and passed off as facts or truth, it can make it harder for people to find things that will actually help them.
It's probably worthwhile to treat medical or mental health advice about alternative treatments that don't have supporting evidence in the form of citations or sources with a healthy degree of skepticism. Some of such information may be true, but the best way to find out is to look at research on the topic and read about the findings.
I don't intend to begrudge anyone who finds these remedies helpful, but when it's shared with others it stops just being a personal choice and starts to medical advice- and medical advice without supporting evidence is best avoided.
That being said, the illustrations and art style are really lovely, and if anyone knows of supporting evidence for these claims, or just has any knowledge of research supported remedies from nature they'd like to share their excitement about, I would be very pleased to hear about them!
