Botanical name: 

Syn.—Collinsonia; Stone root.
P. E.—Whole root.
N. O.—Labiateae.

Properties: Tonic, stimulant, carminative, alterative, diuretic, diaphoretic and astringent.

Indications: Sense of constriction, pain and constriction with irritation in throat, larynx, bladder and anus; a feeling as if a foreign body was lodged in the part. Pain in the rectum and lower bowels.

Use: Has a special influence on the nervous system and mucous membranes, removing congestion and improving circulation of the capillaries. This influence is most marked in relaxed conditions of the mucous membranes of the throat and lower bowels. A valuable remedy in sore throat, laryngitis, pharyngitis, with relaxed and enfeebled capillary circulation. May be combined to advantage with other indicated remedies in atonic dyspepsia, catarrhal gastritis with defective circulation and irritable condition of the heart from weakness. In hemorrhoids, when indicated, it is our best remedy. In these cases it should be used in small doses. Scudder recommends it in nurse's sore mouth, and no doubt it is effective in such cases where there is relaxed condition with impaired capillary circulation in the parts. It is generally given in doses of 4 to 6 drops, with the exception of hemorrhoids, where ½ to 1 drop doses are more effective than the larger doses.
