My gf has chronic asthma and I feel so bad about her migraines that are linked with nausea and stuffy stuffy nose. is there any herbal liquid or capsules she can take for these problems? If anyone can please help us it would be worldy appreciated. If anyone has any experience with anything like this please answer.

This does not sound like just asthma. maybe she is experiencing allergies in conjunction with asthma? why is she nauseous? What OTC she would take would depend on what else is going on with her asthma. when at the pharmacy I would swing by and speak with a pharmacist.
