IV. PRODUCTION OF ESSENTIAL OILS IN THE UNITED STATES OF AMERICA
It appears that almost every important discovery
in the history of the essential oils is connected with the oil of turpentine. The
first large-scale production of an essential oil in the United States of America
was that of oil of turpentine. There were, naturally, good reasons for this
fact: the enormous areas covered by pine forests, especially in North and South
Carolina, Georgia and Alabama, and the great and steadily growing demand for the
oil at home, as well as abroad.
Although tar, pitch and common turpentine (the
oleoresin) were mentioned as products of Virginia in official reports as early
as 1610 (D. Hanbury in Proc. Am. Pharm. Assocn. 19 [1871], 491), the production
of oil of turpentine in North Carolina and Virginia seems not to have started until
the second half of the eighteenth century. One of the earliest authentic reports
on the production of oil of turpentine in Carolina was given by the German physician
and explorer, J. D. Schopf, in his book entitled "Reise durch einigo dor
mittleren und sudlichen Vereinigten Nordamerikanischen Staaten in don Jahrcn 1783
und 1784," (Erlangen 1788, Vol. 2, 141, 247-252).
In the early nineteenth century, the production
of other essential oils was started in the I'nited States and it is generally assumed
that the oils of three indigenous American plants, of sassafras, of American
wormseed (Chenopodinm anthelmtnticum L.)
and of wintergreen (a closely related and similar oil can be obtained from the bark
of sweet birch) were, in addition to oil of turpentine, the first oils to be produced
in the United States of America. The oils of wintergreen and American wormseed have
always boon hold in especially high esteem on the North American continent. It was
by their introduction into the first ''United States Pharmacopoeia," published
in 1820, that, for the first time, both oils were given official recognition. Of
oil of wintergreen, Jacob Bigelow tells in his "American Medical Botany"
(Boston 1818, Vol. 2, 31) that it is "kept for use in the apothecaries shops."
No loss a person than the apothecary, William Proctor, Jr. called "The Father
of American Pharmacy" identified the principal constituents of the oils from
wintergreen (Gaulthcria procumbens L.)
and from the bark of sweet birch (Betula lenta
L.) already hinted at by Bigelow. The use of wintergreen oil for medicinal,
cosmetic and flavor purposes has been nowhere so popular as in the United States,
and yet there is no evidence whatsoever of a production of wintergreen oil on a
commercial scale before or until shortly after 1800.
The same holds true as to the essential oil of
American wormseed. Benjamin Smith Barton mentions the wormseed plant in his "Collections
for an Essay Towards a Matcria Medica of the United States" (Philadelphia,
1798, 40 and 49) in the rubric "Anthelmintics." He states that "it
is the seeds that are used" and does not mention the oil. James Thatcher in
"The American
New Dispensatory" (Boston, 1810, 99) tells
that "the whole plant may be employed" as an anthelmintic, and that "sometimes
the expressed juice is used." In general, however, the seeds "are reduced
to a fine powder, and made into an electuary with syrup." He repeats the same
statement in the second and third editions of his book (1813 and 1817) ; and it
was not until 1821, i.e., after the issuance of the U.S. P. 1820 listing Oleum chenopodii, that Thatcher, in the
fourth edition of his dispensatory (pp. 173-174), added to the above cited text
the following passage: "The essential oil of chenopodium or wormseed is found
to be one of the most efficacious vermifuge medicines ever employed." Any large-scale
production of American wormseed oil had in all probability not taken place
before the twenties or even thirties of the nineteenth century. In the course of
a controversy concerning the quality of the oil prepared from plants grown in Maryland
and in "the western states" about 1850, we are told that "about
twenty or thirty miles north of Baltimore, some fifty or sixty persons grow the
plant in small or large patches on their land" for the production of
essential oil (Am. J. Pharm. 22 [1850], 303).
Apparently there existed on the North
American continent a large-scale production of oil of peppermint prior to any remarkable
American preparation of the other essential oils mentioned. Until quite recently
it was generally assumed that the distillation of American peppermint oil on a commercial
scale had its origin in Wayne County, New York, in 1816. We know now that such an
industry must have been in existence at least as early as 1800. In the booklet "150
Years Service to American Health," published by Schieffelin and Company, New
York, in 1944, we are told of an offer of "homemade oil of peppermint"
made by "Dr. Caleb Hyde, Physician and Druggist, Lenox, Berkshire, Mass."
to Jacob Schieffelin, in 1805. The addressee answered as follows :
"The oils of peppermint
and common mint has (sic) in consequence
of the large quantities made in the United
States become
a mere drug in our market
and no sale for it I have exported
a
quantity it has lain
for years in England without
a purchaser
and I shall eventually become
a loser thereby."
The oils of turpentine and of peppermint were
not only the first essential oils to be produced on a commercial scale in the United
States but they have been up to the present among those that rank first in the quantity
produced. Others, such as oil of orange, lemon, grapefruit, etc., will be described
elsewhere in this work.
