The Pine agaric, Pol. pin., like the Larch agaric, Polyporus officinalis
(described in this work as Boletus Laricis, its older and less correct name), was proved by Dr.
Burt. The symptoms of the two have a very close resemblance, and many are common to both.
Despondency; aching distress in many parts; stiffness of back; of fingers; enlarged tonsils with
dysphagia and constant inclination to swallow; neuralgic pains in head, face, and temples; pain in
liver and spleen with diarrhoea or constipation and piles—these are the chief features of the
proving. Hale says it is a remedy for ague in the Middle and Southern States, taken during the
intermission macerated in whisky. Quotidian fevers, he says, are most suited to it. The symptoms
are < by motion; by walking; > by rest. < In damp air. < After stool.
