Will a true Christian Scientist administer the Epi-pen (epinephrin) to someone who's airway is closing up due to an an allergic reaction?

I'm not sure what is meant by a "True Christian Scientist" but Jesus said "If one of you has a child or an ox that falls into a well on the Sabbath day, will you not immediately pull it out?"

We are given the Sabbath for our benefit, and so too, Christian Science is for our benefit.

A hammer, though a tool meant for good, may be used to harm a person. So too, rules can be mis-applied to harm. The fact is, if a person realizes their life is in danger, they may produce enough adrenaline on their own such that an epi-pen is not needed. When people come to rely on Big Pharma for the relief of their every symptom including side effects of the drugs provided, this is no less a dysfunctional dependency than drug addiction.

The proper application of the herbs God provided us along with know-how of splints and bandages is good.

God says not to eat pork because it's unclean. Atheists laugh, eat pork, then find their arteries are clogged. What do they do then? They go pay Big Pharma for drugs to regulate their blood pressure. The fool pays for his foolishness.

A person gets cancer and decides to put his faith in modern medicine. He is poisoned, irradiated, and cut up. He dies anyway. Yet people don't blame the doctors even though they don't know how much longer he might have lived if he'd only gone on a strict vegan diet.

There is evidence that eating animal protein feeds cancer. Normal cells can use plant protein just as well, but cancer cells cannot use plant protein. Yet doctors will actually prescribe milk shakes such as boost to cancer patients to help them recover from the irradiation, chemo poisons, and surgery. Cancer cells thrive on milk.

The doctors get paid more the more 'treatments' they can give. So it's in their best interest that the cancer recovers. If a person lives for three years after treatment is begun, that is considered success. Yet we don't know that they wouldn't have lived longer without the treatment. Are doctors killing their patients for money when they prescribe Boost and other milk shakes?

If they didn't - they should be tried for murder due to negligence, and their religious beliefs should not be allowed to save them from whatever punishment they would face.

And in the off chance they are right about 'god' existing, I'm pretty sure 'he' would agree.

Christian Scientist is another name for Curch of Christ & Latter day saints (Mornones) and there is no reaosn why they would not use an epiPen if they had to because epinephrine is a human hormone and it's not a foreign material. As a christian (catholic) I have no option as my daughter carries an epiPen due to a severe egg allergy.

As a christian, I would. though i am not a scientist as per your question. We are allowed to use medicine.
