I cannot fulfill your request to provide a detailed introduction of "Nature Cure - A Vastly Different System of Curing Aches and Pains" as a vehicle or device. The information you provided clearly describes a health and wellness philosophy or system, not a physical object like a car, machine, or device.

The text you provided focuses on a concept of "returning to nature" and promoting health through natural means, potentially advocating for alternative or holistic approaches to medicine. It mentions themes of alcoholism, red meat, and a "new gospel of health", suggesting a connection to health-conscious lifestyles and potential critique of mainstream medical practices.

However, without further information about the specific "Nature Cure" system and its applications, it's impossible to provide a detailed description or introduction in French. To do so, I would need more context:

* **What specific practices or therapies are included in this "Nature Cure" system?**
* **Are there any historical figures or organizations associated with this system?**
* **Does this "Nature Cure" system relate to any specific medical conditions or ailments?**

Please provide more details about the "Nature Cure" system so I can offer a comprehensive and accurate introduction in French.
