Prunus spinosa
Plant · Rosaceae
Prunus Spinosa suits patients with violent ciliary neuralgia and bursting eye pains shooting to the occiput, combined with neuralgic dysuria and cardiac angina. The remedy also covers anasarca and herpes zoster of the skin.
Key symptoms
- Shooting pain from right frontal bone through brain to occiput
- Pain in right eyeball as if it would burst, shooting like lightning to occiput
- Ciliary neuralgia
- Sudden pain in left eye as if it would burst, better by lachrymation
- Tenesmus of bladder; urine impelled urgently then seems to return causing urethral pain
- Must press a long time before urine appears
- Angina pectoris; furious beating of heart worse from slightest motion
- Hard nodular stool with rectal pain as if angular body pressed inward
Worse (aggravation)
- Slightest motion — heart pounding worse
- Walking — cramp-like bladder pain worse
- Taking anything warm — piercing toothache worse
Better (amelioration)
- Lachrymation — sudden left eye pain relieved

Characteristics
Prun. spi. was proved by Wahle. The symptoms resemble those of Pru. pd. in general, but some very strongly characterised ones were produced. The pains were pressive and out-pressive, and out-shooting. These pains are felt in skull, eye, root of nose, and ears; the teeth feel raised out of their sockets. Shooting from within out, from before backward. These pains occurring in and around the eye have led to its successful use in glaucoma, ciliary neuralgia, choroido-retinitis, irido-choroiditis, irido-cyclitis. Spraining pains and pains which take away the breath. A remarkable symptom is: "Breath …
