Sanguinaria in Cluster headache

Cluster headache is severe episodic unilateral headache for 15min to few hours. It starts so sudden and reaches peak that there is no time for medication to act. Preventive medication is still the best way to control it.
I keep on trying homeopathic medication whenever I feel it may work. Last month I saw three cases of cluster headache. Last case came back thanking me that Sanguinaria has worked like magic. His headache has gone after first dose. He was male of 30s, headache was severe but at any time of the day on the right side of the head, no medication was working. This was his first episode.
Following are the indications of Sanguinaria:

Sanguinaria: headaches on the right side. Starts in the back of the head and travels upwards to settle over the right eye. Sometimes with a flush of the face, redness of cheeks. These headaches often appear in a regularly timed pattern and are worsened by motion, light, odors and noise
