Uses

The Hopi tribes used the pollen of S. Scaposum, by grinding the flowers with corn to make blue meal (blue pollen). Seldom used internally and only when prescribed by physicians of experience.

The flowers and leaves were extensively used in the United States army during the rebellion to kill lice and it is pretty well authenticated that the same substance forms the basis of many preparations offered for the destruction of all noxious insects whose room is better than their company. Dr. Brown: “A tincture of the seeds, it is said, will cure Asthma and Dropsy, also a specific for cholera morbus.”

Dose

1 oz. of the seeds added to 1 quart of diluted alcohol makes the tincture, of which 10 drops may be given three times a day. This, however, should be used only in extreme cases, and with the approval of persons of knowledge on the subject.

Russian Experience

Szivokost, or Alive Bone, is Russia’s Larkspur. They use the herb and flower, but with caution, as Delphinium is very poisonous. However, it has its useful place in Herbal practice if the “how and when” are observed.
