GERIATRICS
Many are the circulatory disturbances: one time there is marked chest oppression with the sensation as if the heart were squeezed with an iron hand, in which case Cactus is the indicated remedy. Another time we find an irritable heart action and some- what trembling palpitation; here Crataegus in tincture or low potency should be given, which calms the nerves and sustains the heart.
