According to Ayurveda, the universe is formed from five basic elements. These are Ether, Air, Fire, Water, and Earth. As we are a part of this cosmos, these five elements also exist within everyone but to a varying degree. The combinations of five elements form the three bodily humors or doshas: Vata (space and air), Pitta (fire and water), and Kapha (water and earth). The doshas are types of energy and are present in every cell of the body. They govern all the processes happening within the body. 

Doshas

 The three doshas (Vata, Pitta and Khapha)  are the three basic principles that govern the physiological  processes.

When they are in equilibrium keep the body in good health, when they are not in equilibrium, are the three basic causes of the imbalance, disorders, and diseases of the body.

A Dosha (doṣa), according to Ayurveda, is one of three bodily humors that make up one's constitution. These teachings are also known as the Tridosha theory.

The central concept of Ayurvedic medicine is the theory that health exists when there is a balance between the three fundamental bodily humours or doshas called Vata, Pitta and Kapha.

Naturopathy is the art & science that integrates & balances the basis aspects of the body "Chemically, Physically & Electrically," enabling the body’s capabilities to heal itself by following natural methods and making lifestyle changes. 

Integration & balancing life force with the greatest force on earth, Gravity as Medicine, Water as Medicine, Heat as Medicine, Food as Medicine, Time as Medicine, 3600 Postural as Medicine & Earth's electrons as Medicine.

The science behind Naturopathy is not limited to human alone, but to every living things e.g. plant & animal kingdoms that they evolve, adapt & self improvise with time, condition and situation. Animals have been practicing herbal remedies since before humans existed. Animals like birds, bees, lizards, elephants, and chimpanzees have been known to self-medicate. They do this by ingesting or applying plants and natural substances. 

Interestingly, plant can hear, feel, adapt, defend, maintain, manipulate animal species.
