The factory that manufactures a car also has the ability to fix the car, most of the time.
If it's so totally damaged, they'll say, “No, we can't fix it. You have to redo everything.“
Like that, certain diseases can definitely be healed by the mind, but for certain other things, you have to take medication.
Nature as healer
That's why nature has provided so much fauna and flora, herbs.
I don't think nature would say that only through consciousness can you heal everything. Nature need not have taken so much pains to create so many herbs and the science of Ayurveda, which the ancient Rishis have downloaded.
Why would they do that otherwise? Did they say, “Oh, just do pranayama and meditation. All will be healed.” No, they never said that!
Yoga can refine speech

Patanjali also spoke about grammar, and what and how to speak.
Speech matters very much. It can create turbulence or happiness in other people. It can create good emotions or a foul smell and foul feelings. Positivity and negativity come only through speech.
With yoga, the impurity of the mind will disappear. By refining your speech, you can improve your life.
When there are impurities in the body, a purification process has to be done through herbs and medicines.
Maharishi Patanjali elaborated on and expounded on all branches of knowledge, discussing all the needs of human society.
