I. BARK: Volatile oil 6-9 p.c., Sassafrid 9 p.c., tannin 6 p.c., resin, starch, gum, wax, ash 30 p.c. II. PITH: Gum, volatile oil.

Oleum Sassafras. Oil of Sassafras. -- This volatile oil distilled from the root (better -- root-bark) with water or steam, is a yellow, reddish-yellow liquid, characteristic odor and taste of sassafras, soluble in 90 p.c. alcohol (2), solution being neutral, sp. gr. 1.070, dextrorotatory; contains chiefly safrol, CHO2, 80 p.c., pinene and phellandrene, CH, 10 p.c., d-camphor, 6.8 p.c., eugenol, CHO2, .5 p.c., cadinene, residue 3 p.c.  Should be kept cool, dark, in well-stoppered, amber-colored bottles.  Dose, mj-5 (.06-.3 cc.).

Sassafrid. -- Supposed to be altered tannin, the result of oxidation, analogous to cinchona-red; some disclaim its presence in fresh bark; crystallizes in yellowish-brown granules, soluble in alcohol, insoluble in ether, solutions colored red by alkalies, precipitated by aklaline earths (carmine-red), ferric salts (greenish-brown), lead acetate (white) indodorous, nearly tasteless.

Unoff. Preps.: BARK: Fluidextract, 3ss-12 (204 cc.).  Infusion (Tea).  Dose, ad libitum.


Alterataive, diaphoretic, stimulant, emmenagogue.


To purify blood, skin diseases, rheumatism, syphilis.  Infusion valuable antidote for poison-ivy, internally and externally; it (tea) was popular at one time for so-called thinning the blood (alterative) in spring; given with sarsaparilla, guaiacum, mezereum, etc.; oil popular flavoring agent in confectionery, drinks, soaps, etc., antiemetic, antagonist to narcotic effect of tobacco, hyoscyamus, etc.

Derivative Products

1. Safrolum, Safrol, CHO2 -- CH0H(OOCH). -- This chemically is the methylene ether of allyl pyrocatechol, occurring in the oils of camphor, star-anise, cinnamon, etc., and constitutes 80 p.c. of the oil of sassafras.  It is obtained chiefly from the red oil of camphor by collecting that fraction boiling at 230 degrees C. (446 degrees F.), purifying the same by repeated chilling and crystallization; it is a colorless or faintly yellow liquid, sassafras-like odor, sp. gr. 1.105, optically inactive, cooled to - 20 degrees C. (-4 degrees F.) solidifies to a mass of crystals, melting at 11 degrees C. (52 degrees F.), soluble in alcohol (1), 70 p.c. alcohol (30), miscible with ether, chloroform, boils at 233 degrees C. (451 degrees F.); heated with alcoholic potassium hydroxide solution forms isosafrol, which is less toxic than safrol; with bromine yields crystals of CHBrO.  Reduces arterial pressure by depressing vasomotor center; taken a long period produces fatty degeneration of heart, liver, and kidneys; it is eliminated as piperonalic acid.  Dose, mj-2 (.06-.13 cc.).

2. Sassafras Lignum, Sassafras Wood. -- Contains little volatile oil; used like the bark, but very weak medicinally.
