L-Arginine for Migraines

Has anybody tried this or just L-Arginine for headaches:
"Migraine headache. Taking L-arginine by mouth along with the painkiller ibuprofen seems to be effective for treating migraine headache. This combination sometimes starts to work within 30 minutes. But it’s hard to know how much of the pain relief is due to L-arginine, since ibuprofen can relieve migraine pain on its own."

I got the information from the Natural Med. Comphrensive Data Base.
