Anxiety is a feeling of unease, nervousness, or fear that can be mild or severe. It is a natural response to stress or danger, but when it becomes chronic or overwhelming, it can interfere with daily life. Symptoms of anxiety may include racing thoughts, restlessness, muscle tension, sweating, and a sense of impending doom. While there are several conventional treatments available for anxiety, such as therapy and medication, some people may choose to supplement their treatment with natural remedies.
