Botox seems to help with the symptoms of anxiety. Scientists from California found Botox injections can reduce anxiety by up to 72 percent, regardless of where it is injected. Botox is a medication derived from a bacterial toxin, and is injected to relax wrinkles, help stop migraines, muscle spasms, excessive sweating and incontinence. It’s not clear exactly how it reduces symptoms of anxiety, though researchers speculate that the toxins from the medication may be transported to the regions of the central nervous system involved with mood and emotions. Another possibility is that Botox simply lowers anxiety by treating the conditions that it is known to help with. Study authors say clinical trials will be needed to establish the best site and dose to administer Botox specifically for anxiety.
