I do not consider toxic plants to be
"medicines."
Most plants that have become, over many hundreds (if not thousands) of
years, "medicinal" have become labeled as such by cautious,
careful, and successful usage. Ancient people watched the effect that natural grazing patterns had on
animals VERY CLOSELY. They figured that if the plant did not harm, for
example, the
rat or mole, (who was so much smaller that human beings,) then it probably
would not kill human beings.
Understandably, on the whole, the good ancients tended
to avoid human testing of unknown substances or possibly dangerous
plants.
Please remember the vital point that those that the art of Natural
Health is a NURTURING and COMFORTING art and should never be used to do harm
to anyone. Please consider, very carefully, the words of the ancient
Greek physician HIPPOCRATES:
"...DO NO HARM..."
We will be posting some interesting historical information about the
Greek physician Hippocrates in the near future at WellLore.
One that utilizes health care skills of any kind to harm is not a
real care provider.
The following list in my article was excerpted based on information shared at the
holisticbird.org website. According to HolisticBird.org, "the
following list was put together by Dr. James Duke, formerly
chief of the U.S. Department of Agriculture's Medicinal Plant Resources
Laboratory. According to HolisticBird.org,
Dr. Duke got his list from the FDA's unsafe herbs list, from his
own research, and from Dr. Varro Tyler's 'Honest Herbal'. The 'PDR for
Herbal Medicines' concurs with most of these determinations."
According to Holisticbird.org, "cautions are for the herbal and essential oil form of the
plant. When
used homeopathically," the same evaluation may not
apply" to some of the herbs listed herein, (although the accuracy of
this fact has not been
determined.)
Unknown, uncommon, or stange herbs should never be used. Some herbs
should only be used under the care and supervision of a licensed physician.
As with some prescription drugs (like morphine) each herbal medicine
falls within what I have dubbed as The Natural Medicine Safety
Scale. Herbal Medicines, as with Prescribed Medications and
Over-the-Counter Non-Prescribed Medications, fall within a "Spectrum
of Safety," meaning some herbs are as
follows:
1. VERY SAFE
2. SOMEWHAT SAFE
3. LIMITED USE -can be very dangerous if misused
4. DANGEROUS
5. EXTREMELY DANGEROUS, TOXIC, AND LETHAL.
Please wisely note the herbs which are known to be
toxic and stay completely away from them!
In addition to the following research material
excerpted for educational use only from holisticbird.org, we shall
post future educational and research finding about unsafe herbs here at
WellLore. Check back regularly in addtion to reading my article!
THE FOLLOWING LIST IS NOT EXHAUSTIVE, BUT FOR
ILLUSTRATIVE PURPOSES ONLY
Please bear in mind, again, that this
list was excerpted from a Natural Bird Care site; the application
towards humans is obviously not exactly the same, but can provide insight as
to necessary precautions.
