The present invention provides herbal compositions that can prevent or reduce the severity, intensity, or duration of allergic and/or asthmatic symptoms and/or can prevent or delay the development of an allergic or asthmatic response to an antigen. The compositions may optionally include one or more adjuvants, cytokines, encapsulating materials, or pharmaceutical carriers or excipients, and may be administered prior to, during, or after the development of allergic or asthmatic symptoms in sensitized individuals. Alternatively or additionally, the compositions may be administered prior to sensitization to a particular antigen; preferably substantially concurrently with exposure to the antigen.
