~Read the article excerpt then respond to the question below.~
"Scientists make synthetic substances by arranging atoms and molecules in the lab. They use what they know about different types of atoms and molecules to arrange them and make the kinds of substances they want.
Synthetic medicines aren’t any different at the atomic level from the natural medicines found in the rainforest. After all, molecules are just molecules—whether they’re made in nature or in a lab, the same types of atoms arranged in the same ways always form the same molecules that behave in the same ways."

At the atomic level, are synthetic medicines different from natural medicines?
Explain your thinking.

Answers

Although herbal medicines are less potent in comparison to synthetic drugs in some cases but still these are consider less toxic or having less side effect in contrast to synthetic drugs. The ultimate norm for any medicine (human made or natural) is their non-toxicity, effectiveness, specificity, stability and potency.
