Ginger is an herb. The rhizome (underground stem) is used as a spice and also as a
medicine. It can be used fresh, dried and powdered, or as a
juice or
oil.
Ginger is commonly used to treat various types of "stomach problems," including motion sickness, morning sickness,
colic, upset stomach, gas, diarrhea,
nausea and vomiting after surgery, as well as loss of appetite. Other uses include treating upper respiratory tract
infections,
cough, and bronchitis.

A double-blind placebo-controlled pilot study of sublingual feverfew and ginger (LipiGesic? M) in the treatment of migraine. 1. headache. 2011 Jul-Aug;51(7):1078-86. doi: 10.1111/j.1526-4610.2011.01910.x. Epub 2011 Jun 1. 
BACKGROUND: Therapeutic needs of migraineurs vary considerably from patient to patient and even attack to attack. Some attacks require high-end therapy, while other attacks have treatment needs that are less immediate. While triptans are considered the "gold standard" of
migraine therapy, they do have limitations and many patients are seeking other therapeutic alternatives. In 2005, an open-label study of feverfew/ginger suggested efficacy for attacks of
migraine treated early during the mild
headache phase of the attack. METHODS/MATERIALS: In this multi-center pilot study, 60 patients treated 221 attacks of
migraine with sublingual feverfew/ginger or placebo. All subjects met International
headache Society criteria for
migraine with or without aura, experiencing 2-6 attacks of
migraine per month within the previous 3 months. Subjects had <15
headache days per month and were not experiencing medication overuse
headache. Inclusion required that subjects were able to identify a period of mild
headache in at least 75% of attacks. Subjects were required to be able to distinguish
migraine from non-migraine
headache. Subjects were randomized 3:1 to receive either sublingual feverfew/ginger or a matching placebo and were instructed but not required to treat with study medication at the earliest recognition of
migraine. RESULTS: Sixty subjects treated 208 evaluable attacks of
migraine over a 1-month period; 45 subjects treated 163 attacks with sublingual feverfew/ginger and 15 subjects treated 58 attacks with a sublingual placebo preparation. Evaluable diaries were completed for 151 attacks of
migraine in the population using feverfew/ginger and 57 attacks for those attacks treated with placebo. At 2 hours, 32% of subjects receiving active medication and 16% of subjects receiving placebo were pain-free (P= .02). At 2 hours, 63% of subjects receiving feverfew/ginger found pain relief (pain-free or mild headache) vs 39% for placebo (P= .002). Pain level differences on a 4-point pain scale for those receiving feverfew/ginger vs placebo were -0.24 vs -0.04 respectively (P= .006). Feverfew/ginger was generally well tolerated with oral numbness and
nausea being the most frequently occurring adverse event. CONCLUSION: Sublingual feverfew/ginger appears safe and effective as a first-line abortive treatment for a population of migraineurs who frequently experience mild
headache prior to the onset of moderate to severe
headache.
