In May 1808, the Peabodys moved to
Salem, Massachusetts, where wealthy families were potential clients for Peabody's medical practice and Eliza's school. Eliza had entry into society as a member of an intellectual family and granddaughter of General
Joseph Palmer of the
American Revolution. Salem was a port town with "sleek sailing ships", brick mansions, wealthy merchants, and the
Salem Athenaeum library. Unfortunately, the
Embargo Act of 1807 against France and England stopped most sailing voyages from Salem and reduced revenues for merchants. The family lived predominantly in Salem from 1808 to 1840, with two years in
Lancaster, Massachusetts from 1820 to 1822 and in Boston from 1828 to 1840. Peabody's brother Captain John Peabody, married in 1807 to Elizabeth Manning, lived in Salem. They spent time together, enjoying their growing families and supporting one another. John loaned Peabody money as he built his medical practice. When John was sailing for months at a time, Peabody looked in on his wife. Eliza operated a school and boarding house for girls out of the family's row house along Union Street. She engaged young women who received an education and a place to live in exchange for their domestic work. In 1817 and 1818, Peabody sat on the Salem School Committee. In 1834, he managed the Salem Lyceum.
Medical practice In 1811, Peabody became a member of the
Massachusetts Medical Society. Although he had not attained a medical degree, he may have been accepted due to his training under Dr. John Jeffries and having five years experience in his medical practice. Peabody was the secretary for the Medical Society in 1817. In the 1820s, Peabody adopted homeopathic medical practices of Dr.
Samuel Hahnemann of Germany. Rather than leaning on
emetics and
purgatives that were considered "heroic" practices, Peabody adopted the use
sassafras,
belladonna,
henbane,
horehound,
aconite, and snake venom to treat patients. The medicines were administered in small doses so that patients did not have the ill effects and potential deaths from large doses of medicine used in heroic practice.
Dental practice Peabody also worked in the relatively new practice of dentistry, experimenting with new dental practices. While the family lived in Boston, Peabody kept a dental office in Salem. Peabody published the book,
The Art of Preserving Teeth, in 1824. In the 1830s, Peabody used hypnosis as a pain management technique for extractions. By 1837, Peabody had a dental practice and lived on Charter Street, near the Charter Street Burying Point (now in the
Charter Street Historic District). ==Boston==
