PHYSIOLOGICAL ACTION.— The pathogenesis of Thuja was published by 
Hahnemann in the fifth volume of the Reize Arzneimittellehre. 
“The Austrian provings, which are entirely confirmatory of Hahemann’s, show 
that the main action of Thuja is on the genito-urinary organs, with the anus, and 
on the skin. It causes copious and frequent urination; burning in several parts 
of the mucous tract; pains of various kinds in the penis; inflammation of the pre- 
puce and glans; ulcers, tubercles, and other excrescences on the sexual organs, 
with itching and’ profuse sweating; and, in the female, leucorrhcea. The sexual 
appetite was depressed, and the catamenia retarded. Burning, itching, swelling, 
and mucous discharge occurred at the anus; and on the skin generally, but espe- 
cially in the ano-genital region, tubercles and warts were developed. In the neigh- 
boring mucous membranes similar phenomena appeared, but naturally of moister 
character.” t 
The action of the drug in causing great flatulence and distension of the abdo- 
men, with rumbling and colic, leads us back to Bocclerus, who says,§ “Folia (thuj@) 
resoluunt, exsiccant, flatus pellunt,’ etc.; while the excessive chilliness, heat, and 
profuse sweat, point to a remedy often indicated/in intermittent fevers. The 
peculiar action of this drug is one difficult of explanation,
