Reliable data on yield are not available, although some estimates place the yield at about 450 pounds of dry root per acre. The American market is supplied with imported aconite root, for which the prewar price ranged from about 9 to 15 cents a pound. The price in June, 1920, ranged from 60 to 62 cents a pound. The quantity imported in 1919 was about 35,000 pounds. The demand for this drug is limited, and this fact, together with the probable low yield, makes its profitable cultivation in this country very doubtful. ALTHAEA. Althaea, or marshmallow (_Althaea officinalis_), is a perennial herb introduced from Europe which now grows wild in marshy places near the sea in Massachusetts and along tidal rivers in New York and Pennsylvania. The root forms the official drug, but the leaves and flowers also are sometimes used medicinally. Althaea will grow well in almost any loose garden soil of moderate fertility, but tends to winterkill in situations where the ground freezes to a considerable depth. The plants may be propagated from seeds or from divisions of the old roots made early in the spring. The seed may be sown in the open in shallow drills at least 3 feet apart, and the seedlings should be thinned to stand 16 inches apart in the row. Under good conditions the plants attain a height of 3 or 4 feet; therefore, close planting does not give sufficient room for full development. In the second year of growth the roots are harvested, washed, peeled, cut into short lengths, and thoroughly dried. Yields at the rate of 800 to 1,000 pounds of dry root per acre have been obtained. The prewar wholesale price usually ranged from 12 to 20 cents a pound. The price in June, 1920, was 25 to 27 cents a pound. The annual importation of this root averages about 30,000 pounds. In view of the amount of hand labor required in preparing the root, the relatively low price, and the rather limited demand, the cultivation of this plant for profit is not very attractive. ANGELICA. Angelica (_Angelica officinalis_) is a European biennial plant of the parsley family, sometimes grown in this country as a culinary herb and known commonly as garden angelica. The fresh stems and leafstalks are used as a garnish and for making a candied confection. The seeds and the oil distilled from them are employed in flavoring, and the aromatic roots are sometimes used in medicine.
