General tonics are used to promote balance and resilience in the body, offering gentle, long-term support to improve energy, well-being, and systemic function. These substances are often adaptogenic or nourishing, helping the body adapt to stress, recover from fatigue, or maintain optimal performance. Common examples include herbs like ashwagandha (Withania somnifera), ginseng (Panax ginseng), and nettle (Urtica dioica), which are valued for their ability to enhance vitality across multiple body systems.
