14. Aloe Vera
Typically, Aloe Vera is used today to treat skin problems such as burns and it happens to be used in a lot of different cosmetics. Of course, Aloe Vera is nothing new. It has been used in some form for thousands of years. Aloe itself comes from plants that can grow in many areas.
It can be traced back to 1500 BC in Ancient Egypt, who likely used it for their skin troubles and early cosmetics. It is even mentioned in the Dioscorides’ De Materia Medica by Greek Physician Pedanius Dioscorides from the Mid-1st Century AD. On top of this, the Juliana Anicia Codex of 512 AD refers to it as a useful skin helper too.
