I think the issue might be that we feel we need to travel to distant lands to meet people who know their local plants this intimately.
The local cultures where most Internet-users live are more dependent on global trade, rather than intimate local knowledge.
There've also been concerted efforts to demonize, exterminate, and discredit indigenous medical knowledge.
Some distant cultures have retained their cultural knowledge of which local plants are useful in what ways, or how to research plant-based medicines by direct observation instead of pharmaceutical extraction.
We also tend to segregate the remaining herbal lore. Reliable medicines are often refined to white purity and converted to concentrated pills or powders, making their botanical origins hard to recognize or honor.
Powerful 'magic bullets' like antibiotics are used indiscriminately, for example in antibacterial hand soap. We believe that if something is "good," more is better; patients expect a quick, chemical cure.
The remaining field of herbal medicine is crowded with 'alternative' devotees who don't like this approach. Maybe because it failed to treat a complex condition, or maybe because it doesn't fit with their personal philosophy or beliefs, or sometimes out of deep and abiding interest in a more direct or natural approach. But a whole lot of these folks have little or no training - either scientific or tribal.
In their zeal, the Alternative Believers often muddy the waters by embracing snake-oil and unreliable cures, or being easily convinced by a sham 'proof'. For example, my mother-in-law recently got excited about a gallbladder-stone "removal" remedy that has been widely discredited. It makes it harder to share her excitement about other 'cures' she's researching, like anti-cancer foods and remedies. (I will eat all the fresh fruit juice you like, but I won't believe it's curing me of anything without some further proof.)
Another friend was surprised to discover that their 'diagnostic' test produced the same "telltale" results regardless of whether there was a person present in the testing setup.
It was a system that was supposed to 'diagnose toxins': the patient puts their feet in a bath, the system runs a mild electrical current through a special electrolyte solution. If the solution darkened, it meant that the person had 'toxins' which could be treated with the other proprietary equipment. With the owner's permission, we tried running the diagnostic in a clean bath with no feet in it. The solution darkened identically.
My simplest explanation would be that the dramatic effect was due to the current and electrodes interacting with the solution; it would not be hard to duplicate with metal salts that have colored and clear forms. I can't help but think the 'test' was developed by someone who knew the chemistry, and was deliberately defrauding the users. Our friend who had just bought the equipment and wanted to become a healing practitioner had been sold on the idea without the curiosity or skepticism to question the process.
Many, many people do not seem to have
enough direct observation skills, scientific training, or skeptical curiosity to verify a result.
Quackery is often more dramatic than genuine healthy practices, and seems to thrive on the Internet as well as word-of-mouth. Fortunately, the Internet also makes it easy to pass along warnings. My first response to new 'cures' is to google the name or ingredients of the cure, plus "hoax" or "fraud," and see if anything comes up. I don't trust all fraud warnings any more than I trust all miracle cures, but at least if there's a controversy I will be informed.
Other friends credit 'ancestors' with imparting ancient wisdom, but prefer to re-invent their particular field rather than interact with living, experienced elders.
I am honored to have access to several more-experienced elders, and friends who've studied natural and traditional as well as conventional medicine, who can help me sort fact from fantasy.
The unreliable reputation of the whole 'alternative' field then creates a division of opinion: dogmatic skeptics won't try it, and dogmatic believers or credulous folks will try anything without regard to reliability.
Good information from non-academic sources can be hard to find in all the noise.
In other words, we have made herbal medicines into a matter for religious belief, not reasoned debate or observant testing.
I don't mean to offend anyone on this site; I know a number of people here who do practice alternative health and herbal medicine with excellent, well-researched success, and are careful to do no harm.
When I do get a chance to discuss herbal medicines with reliable sources, I'm hard-pressed to absorb enough information in these brief encounters.
I suspect the training period to fully understand and practice effectively may be as long or longer than a Western MD's medical schooling.
But we can learn a little bit at a time, and become better first-aid and home-care resources for ourselves and our families.
I agree that we have great resources in our climates and regions.
We have more
medicinal plants in our landscape than I know what to do with -
I harvest and use yarrow and Oregon grape for things like pet skin infections, and have learned to identify various rose-family plants, balsamroot, and a few others.
I use astringents (rubus berry leaves / buds) and demulsents (chickweed, licorice) to manage minor digestive upsets or uncomfortable menstrual flow.
I would love to know more about plants that regulate blood sugar as I'm not diabetic but prone to hypoglycemia - but this, even more so than diabetes, can definitely be managed with good dietary habits.
If there was a way to reduce my sensitivity so that I could fast for a day or two, or eat snacks containing refined sugars, without ill effects, I'd love to learn it.
However, it might just be that eating a healthy diet is a basic requirement for staying, and feeling, healthy.
That's one of those inconvenient facts that tends to crop up when considering holistic or systemic interactions. Sometimes there's no 'magic bullet' medical treatment; the reliable
answer is consistent, healthy practice.
