AMARYLLIS (the name of a girl in classical pastoral poetry), in botany, a genus of the natural order Amaryllidaceae, containing the belladonna lily (Amaryllis Belladonna), a native of South Africa, which was introduced into cultivation at the beginning of the 18th century.
The symptoms of poisoning by belladonna or atropine are dealt with above.
Thus, the Lent lily is Narcissus Pseudonarcissus; the African lily is Agapanthus umbellatus; the Belladonna lily is Amaryllis Belladonna (q.v.); the Jacobaea lily is Sprekelia formosissima; the Mariposa lily is Calochortus; the lily of the Incas is Alstroemeria pelegrina; St Bernard's lily is Anthericum Liliago; St Bruno's lily is Anthericum (or Paradisia) Liliastrum; the water lily is Nymphaea alba; the Arum lily is Richardia africana; and there are many others.
The external uses of the drug are mainly analgesic. The liniment or plaster of belladonna will relieve many forms of local pain.
This warning applies notably to those - usually women - who are accustomed indiscriminately to use belladonna or atropine in order to give greater brilliancy to their eyes.
Whether effected entirely by action on the nerve terminals, or by an additional influence upon the vaso-motor centre in the medulla oblongata, atropine certainly causes extreme dilatation of the blood-vessels, so much so that the skin becomes flushed and there may appear, after large doses, an erythematous rash, which must be carefully distinguished, in cases of supposed belladonna poisoning, from that of scarlet fever: more especially as the temperature may be elevated and the pulse is very rapid in both conditions.
In treating an actual and present attack of asthma, it is advisable to give the standardized tincture of belladonna - unless expense is no consideration, in which case atropine may itself be used - in doses of twenty minims every quarter of an hour as long as no evil effects appear.
Totally to be reprobated is the use, in order to relieve pain, of belladonna or any other application which affects the skin, in cases where the surgeon may later be required to operate.
Belladonna, the Belladonna Lily, 3 ft., has large funnel-shaped flowers in September, of a delicate rose colour.
Irritation is lessened by lotions containing substances that will diminish irritability of the nerve-endings and skin, such as carbolic acid, hydrocyanic acid, morphine or opium, cocaine, belladonna or atropine.
