Acupuncture has a large history which dates 5,000+ years ago – this is now argued to being 2,000 years ago, but there is evidence of this even 5,000 years ago.
The medical books of that time are all clinical proof of acupuncture working – it simply does not get more “proof” enough compared to western medicine – where you have 5,000 years of clinical records.
It is true, that very few understand those records, and if they do, it is not published in english or other languages till this day – this is not due to language problems, but also culture barriers, where some already understood concepts in China and ancient asia, are not even understood by the western world.
The nei jing has been translated by several people – but it still requires background knowledge of acupuncture and the culture of ancient asia, to be able to understand – and often these translators are not medical translators, nor are scholars who have studied the language changes over the years, as well as medical practice – translation of such texts requires intensive study, for years, to even begin to understand a single page of the book – it is not as simple as translating a language from one word to another – as implication of each word, what it is implying, referring to, is lost, during translation – and this can lead to a total misunderstanding of the medicine.
How did Acupuncture form?
Acupuncture was not formed by people testing needles or stone needles on their points, and recording what results they get – this is a popular belief, but this is very premature and almost idiotic – not enough study has been done today, to even understand the complexity of acupuncture.
Is Acupuncture easily that advanced for all diseases today?
This greatly depends on the skill of the individual practitioner as well as the system of acupuncture they practice, and the teachings that were passed down to them by their teachers.
It should be understood, that whilst the western system of medicine is very centralized, in ancient asia, they had the opposite system of decentralization of knowledge – partly due to the fact, the time they lived in, knowledge was not often shared outside your immediate tribe or family – one needs to understand the times to understand fully and beyond concept, why this used to happen – and to some extent, is valid today.
