What sort of background do you have in chemistry and botany? Those would be the main fields you would require for this in non-magical terms, though I will teach you the 'magical' side of that you need to know.
Though I must warn you that, as you lack magic, while you will be able to brew a small number of potions, many still require magic even though I have been able to substitute mundane ingredients for the magical ingredients usually required. However, if you wish to make it your project to discover whether a version of these potions can be developed that does not require magic in order to brew them, I would highly approve.
