Ayurveda - A Branch of Veda
Ayurveda is deeply rooted in Vedic thoughts. It is a part of the Vedas, the science of knowledge on health or "Ayur". This is why in Ayurveda, apart from administering herbal medication, a patient integrates yoga and meditation in conjunction with spiritual practice as an ultimate solution. According to the Vedas, to be "spiritual" means to "enquire" and be free from concepts and wrong beliefs. The spiritual practices of Vedanta are deeply intertwined in Indian culture to give the double benefit of attaining good physical and mental health and also to accelerate the evolution of man. We started our life on Earth as single cell microbes and later evolved to the penultimate - last but one- state of human body. This will be discussed in detail in Evolution later.
The final step, of course, is to evolve to the level of Pure cosmic Consciousness. This can be achieved only when humans purify all traces of animal tendencies within them and recognize cosmic Consciousness using the human body and mind. Science teaches us that Man evolved to this human form using his intellect. It is the intellect that helped him to master his surroundings more efficiently than his animal counterparts. What is left is to master his own mind to the highest evolved form.
Therefore, in Ayurveda, an individual is not superficially treated for any disease. Disease is understood as a compulsive emergency step by the body to turn inward to the mind and eradicate all negative tendencies that hinder the evolutionary process. As a result, preventive measures in the form of health secrets were ingrained in Indian culture in daily life to attain sound physical and mental health. Sound physical and mental health is achieved only through strengthening of the intellect which then becomes conducive to further spiritual enquiry of life.
It is a pity that when Man is confronted with any physical disease or ailment, his immediate focus is an external agent or cause , ignoring the very mind that is the root cause. The word "Man" comes from the root word "Mana" which means mind in Tamil and Sanskrit languages.
We will start to discuss how the mind leads to diseases and how the same mind when treated brings peace to us.
Siddha and Ayurveda the source of Homeopathy
Before Hahnemann: How Tamil and Ayurvedic Medical Knowledge Reached Germany
Building the Indirect Evidence for Homeopathy’s Indian Origins
Part 1: The Principle Existed in India Long Before Hahnemann
The founding principle of homeopathy — Similia Similibus Curentur, or the Law of Similars — was not new when Samuel Hahnemann formalized it in 1796. Ancient Indian physicians had already articulated it. The Charaka Samhita, one of the oldest foundational texts of Ayurveda, documents two approaches to healing: Vipareetha Chikitsa (treatment by contraries) and Tadarthikari Chikitsa (treatment by similars). The Sanskrit saying “Vishasya Vishamoshadhi” — poison is the remedy for poison — encapsulated this principle long before European medicine discovered it.
The Charaka Samhita is attributed to a period between the 2nd century BCE and 2nd century CE. Hahnemann was born in 1755. The principle predates him by nearly two thousand years.
Part 2: The German Missionaries Who Came to Tamil Nadu
This is where the story of indirect transmission begins — and the historical record is clear.
Bartholomäus Ziegenbalg was a German Lutheran missionary, born in Pulsnitz, Saxony, and the first Protestant missionary to arrive in India. Sent under the patronage of Frederick IV of Denmark, he co-founded the Danish-Halle Mission in Tranquebar (present-day Tharangambadi, Tamil Nadu) in 1706. 
Crucially, Ziegenbalg did not come merely to preach. He immersed himself in Tamil knowledge. From the outset of his stay in Tranquebar, Ziegenbalg began collecting Tamil palm-leaf manuscripts. He acquired close to 300 manuscripts covering a range of topics including history, poetry, traditional medicine, Hindu philosophy, ceremonies, and rituals. 
Within two years of arriving in India, Ziegenbalg had compiled the Bibliotheca Malabarica — a catalogue of 161 Tamil books he had read, describing the content of each. 
He catalogued these works in German, in a document titled Verzeichnis der Malabarischen Bücher (List of Malabar Books). This catalogue found its way to the British Museum via Germany, where a large portion of Ziegenbalg’s translations and works were sent after his death in 1719. They formed the earliest basis of Tamil language scholarship in Germany. 
Part 3: Tamil Medical Manuscripts Travelled to Halle, Paris, Copenhagen, and London
The transmission of Tamil medical knowledge to Europe is now a documented area of academic scholarship. A peer-reviewed chapter published by Palgrave Macmillan is titled precisely: “The Circulation of Medical Knowledge through Tamil Manuscripts in Early Modern Paris, Halle, Copenhagen, and London” (Stephen, S.J., 2016, in Histories of Medicine and Healing in the Indian Ocean World).
By April 1713, Ziegenbalg reported holding 237 local Tamil and Portuguese books on religion (Hindu and Islam), medicine, and poetry.  Medical texts were explicitly among his collection.
The University of Halle — where Ziegenbalg studied before coming to India, and to which his manuscripts and translations were sent — was the very same institution that shaped German intellectual life in the early 18th century. Hahnemann was a German physician working in this same intellectual and geographic milieu decades later.
Part 4: Europeans Directly Studied Siddha Medicine
The evidence goes beyond manuscript collection. Europeans who came to India for religious and commercial purposes began to learn the local language, science, and medicine. The major challenge Europeans confronted in India was the management of tropical diseases. Having tried their own medicines without success, they adopted the traditional practices of native Tamil Vaidyas. European herbalists and naturalists learned Tamil and Siddha medical texts and documented their findings in paper manuscripts and other writings. There were numerous Siddha medical treatises translated into European languages including English, German, French, Spanish, and Latin — and these were transferred to various scientific societies across Europe. The Danish-Halle Mission at Tranquebar is one of the most prominent examples of this knowledge transfer in Indian history. 
Part 5: Hahnemann Was German — and Connected to This World
Samuel Hahnemann was born in Meissen, Saxony, Germany in 1755 — just decades after Ziegenbalg’s manuscripts and translations began arriving in Germany and circulating through European academic institutions. He studied medicine at Leipzig, Vienna, and Erlangen — all within the European scholarly network that was actively processing and debating knowledge arriving from India.
He did not need to travel to India. The knowledge had already come to him.
The Conclusion
The argument is not that Hahnemann plagiarized Indian medicine. The argument, supported by documented evidence, is this:
German missionaries arrived in Tamil Nadu in 1706. Within years, they were systematically collecting, translating, and sending Tamil medical manuscripts — including texts on traditional medicine — to Germany and across Europe. These manuscripts circulated through the same scholarly networks that Hahnemann inhabited as a German physician. The core principle of homeopathy, the Law of Similars, was already documented in Indian texts nearly 2,000 years before Hahnemann. The pathway for indirect knowledge transfer is historically established and academically documented.
Hahnemann may have believed he discovered something new. What the evidence suggests is that he rediscovered — and brilliantly systematized — a principle that ancient India had known for millennia.
