where the feet become hot and have to be uncovered for several days until the congestion subsides. Belladonna also has marked dryness of the skin and of all the mucous membranes, yet when this dryness involves the mouth, there is generally little thirst.
Anything that markedly alters the circulation can provoke or aggravate the Belladonna state. Generally, overheating and abrupt exposure to cold can provoke or aggravate the symptoms, not just in the immediate sense but also chronically. One often hears a history of chronic headaches or vertigo, etc., which began after a patient washed his hair and immediately went out into the cold air. Belladonna patients can be either warm-blooded or chilly or sensitive to both heat and cold. Rarely does one find in the constitutional Belladonna extreme chilliness or warm-bloodedness.
The consistent theme is that abrupt temperature changes provoke symptoms by altering the circulation. Belladonna can be adversely affected by exposure to the sun, to overheating from sitting in the sun. It is curious that such apparently vital patients can be so easily discomfited by so mild a stress as entering the cold when overheated. It is as if the intense energetic state of Belladonna is but precariously held in balance, vulnerable to the slightest bit of extra stimulation.
Also, hormonal disturbances may bring about these circulatory changes; consequently, many of the complaints of Belladonna occur around the time of menstruation: before, during, or after. Symptoms may also follow childbirth or hysterectomy.
