Professor Salvador, distinguishes phytotherapeutic from phytopharmaceuticals:
“The plant protection products are medicinal products developed exclusively for medicinal herbal” on the other hand “the phytochemicals are substances extracted from plants […] with pharmacological activities.”
The transformation process from a natural product in a phytochemical begins with the collection of plant material: collecting the plants or their habitat obtained by using cultured cells and plant tissues. Identification and incorporation of vegetable substances in a pharmaceutical formulation follows. Research and procedures (methods and technologies) pharmacists should be validated and legal for the development of a new medicine (such process takes years and requires major investments). It should be noted that, as a product of vegetable origin requires more years of research because there are factors which influence in particular the interaction between the different chemical compounds.
Famous Toxicology quote:
“All substances are poisons: there is no other than a poison! The right dose differentiates a poison and a remedy. ” – Paracelsus (1493 – 1541)
Toxicology is the science that studies the adverse effects of chemicals on organisms.
