in response to All four are used to this day in both allopathic and so-called "alternative" (naturopathic/osteopathic) medicine .

So those who find safer and more effective remedies through naturopaths are not respecting their bodies as temples of the Holy Ghost?

.
I see, I mentioned 3 by name, now you claim "four."
.
If you mean to imply that that (1) arsenic trioxide is used in preference to other chemotherapy agents or is main stream allopathy, (2) belladona extract is used in preference to single components like scopalomine or atropine or alternatives like albuterol, or (3) hemlock is used at all in allopathic medicine, you are desperately "misrepresenting " the truth.
.
(1) Even when it comes to allopathic poisons ("chemotherapy"), arsenic trioxide is a side note in the pharmacopoeia. In almost 50 years I have never seen an allopath use arsenicals even once—or even mention them except to condemn their use. I have seen dramatic cures from marijuana and strongly support its use, but I did not mention MJ among the three, "four."
.
(2) For bladder spasms, bronchospasm, and treatment of bradycardia, safer, more controllable, more effective allopathic drugs are used rather than belladona.
.
(3) As for hemlock, it is relegated to toxicology texts, not to be used ever for any treatment.
.
To be clear, when safer and more effective treatments are available (yes, including marijuana), they should be used.  To prefer hemlock is indeed sinful abuse of the temple of the Holy Ghost.

And all three are used in medicinal drugs, as well as various other natural toxins.

So, when a single chemical from a plant is synthetically produced, you claim that as "natural"???
What a joke.
