Therapy: When blood dyscrasia is present, sluggishness of the digestive apparatus, deficient glandular secretion, impaired secretion of the mucous membranes of the stomach and intestinal canal, this agent is indicated, as, in these cases, its tonic properties are plainly manifested.
It is of value in imperfect restoration of these functions after protracted disease, on which it operates with the tonic and restorative stimulants to an excellent advantage.
Amenorrhea, leucorrhea and dysmenorrhea, with relaxed condition of the uterine supports and prolapsus, sometimes occurring from the extreme debility following severe fevers, and common, also, with scrofula and other blood dyscrasias, are all materially benefited by corydalis formosa.
In chronic skin disorders with marked cachexia, this agent is speedily curative. It will be found superior to other agents in overcoming eczema with great relaxation of tissue and general plethora.
It has been used in all cases of syphilis and scrofula with marked results. In syphilitic nodules of the bones, in syphilitic and scrofulous ulcerations, its influence is direct, immediate and permanent. If there is persistent ulceration with general breaking down of soft tissue, a strong infusion has been applied externally with good results. This is in part due to its stimulating influence upon the emunctories of the skin, facilitating elimination through the glands of this structure.
It has a marked influence, also, upon the kidney function which, while beneficial in its direct influence upon general elimination, is hardly sufficient to enable it to be depended upon as curative of kidney or bladder troubles to the exclusion of the use of more direct agents."
