Bidens Bipinnata—Connata—Frondosa. (Spanish Needles.)

Preparation.—Prepare the tincture from the recent herb, in the proportion of ℥viij. to Alcohol 76° Oj., using pressure. Dose from five to thirty drops.

The different varieties of Bidens deserve investigation. Reference to the Dispensatory or Materia Medica will give the direction it should take. I am especially interested in the action of the B. Frondosa on the heart and circulation.
