Fermentation can either produce Ethyl Alcohol or Lactic Acid, it just depends on what organism you are talking about
Hallucinogens are naturally-occurring or synthetically-produced drugs that can cause hallucinations
ARTIFICAL
A xymophyte is a process of fermentation produced by bacteria, yeasts, or other organisms.
Alkaloids are naturally occurring chemical compounds formed from basic nitrogen atoms. Alkaloids are produced by a large variety of organisms that include plants, fungi and bacteria.
Calcium produced as aminoate complex means that the calcium was synthetically produced. This is the opposite of it naturally occurring.
CFC's are naturally occurring. Some people disagree and say they are completely man made.
Alcohol, in its various forms, can be man-made or naturally occurring. Natural alcohol occurs in small quantities in certain fruits and vegetables as a result of fermentation by yeast or bacteria. Man-made alcohol is produced through processes like distillation and fermentation of crops like grains or sugarcane. The majority of alcohol consumed by humans is produced through man-made methods.
Saltpeter is a salt produced by the solution of nitrates with potassium. It is a naturally occurring deposit known as niter. It can also be produced in a laboratory.
oleoresin
Substantial heat, whether produced by humans or naturally occurring, can melt rock.
Ethanol is produced naturally by yeasts from sugars through a process called fermentation.
A hormone is a naturally occurring substance (chemical) that affects the behaviour or metabolism of other cells through signalling.
