    Description of the substance

    Botanical Information:  Convolvulaceae . This large and well - distinguished family of mostly tropical or subtropical plants, is represented in North America by 8 genera, containing in all 73 species and 17 recognized varieties. The order is composed of herbs or shrubs with stem that generally twine or trail.  Leaves  alternate, petioled (absent in  Cuscuta );  stipules  none.  Inflorescence  truly axillary, the peduncles 1 - flowered or cymosely 3 - many flowered;  flowers  regular and perfect, 5 - merous or rarely 4 merous.  Calyx  persistent;  sepals  mostly distinct, imbricated.  Corolla  with an entire or lobed limb.  Gynoecium  generally 2 - carpelled.  Stamens  as many as the lobes of the corolla and inserted low upon its tube.  Hypogynous disk  evident, annular.  Ovary  2 to 6 - celled;  style  single, sometimes divided;  stigma  terminal or introrse.  Fruit  capsular or fleshy;  seeds  comparatively large;  embryo  filling the testa;  albumen  mucilaginous, surrounding, or surrounded by, the embryo.
         In this order our proven plants are: The Oriental Scammony ( Canvolvulus Scammonia , Linn.), whose root yields an irritant but nearly tasteless purgative, often given to children as an anthelmintic on account of the smallness of the requisite dose for purging; Jalap, the dried tubercules of the Mexican  Exogonium Purga , Benth., is a certain, powerful and speedy drastic purgative used as above; it has a gripping effect, however, making it less pleasant then Scammony; and Convolvulus Duartinus, the common Morning Glory ( Ipomoea Bona  -  nox , Linn.), a native of the tropics, so extensively planted north as an ornamental "vine. "
         Many other genera furnish plants more or less used in general medicine. viz.; The North Aferican  Ipomoea  Nil, Roth; whose seeds, in 50 - grain doses, prove purgative, and in action greatly resemble, Jalap; the East Indian  Ipomoea Turpethum , R. Br., the Jamaican  I ,  tuberosa , Linn., and the St. Domingo  I .  Cathartica , Poir., are all used in their countries as purgatives, though the latter is generally too strong in its action to be safely given. The leaves of the Madras  Argyreia bracteata , Wall., are used by the natives in decoction as fomentations for scrofulous enlargements. The root of the tropical  Batatas paniculata , Chois,, is cathartic; while those of the East Indian  B .  edulis  are wholesome, and as cultivated in the warmer climates, from an article of commerce known as Sweet potatoes. Our common Bracted Bindweed ( Calystegia sepium , R. Br.) has a purgative root, as has also the European  C .  Soldanella , Rom, & S. Oil Rhodium, a bitter essential oil, used to attract rats and mice to traps, also to adulterate oil of roses, is distilled from the sternutatory wood of  Convolvulus  (Breweria, Rhodoriza)  scoparius , Linn.
               This plant has been used much like Jalap and Scammony, in 40 - grain doses of the jointed and vermiculate roots, as a diuretic and gentle laxative. (Millspaugh’s Medicinal Plants).

    Some Botanical information (Information refers possibly to Convo-s)
         Europe, Siberia, China, Persia, India, Chile, North America.
         Convolvulacee contain (tubers, rhizomes, roots and seeds) laxative heterosis - intestinal peristalsis - and lysergic acid.
         The convolvulus is very sensitive to weather conditions, it always closes when raining and opens again when the sun appears. (it closes during the night)
         The flower is delicate, whereas the plant is strong and spread quickly. It is an infestant plant. Its roots are deep and difficult to extirpate. The branches climb up the objects on which the plant grows (also other plants) except from very big objects (e.g. gates).
         It is a perennial; its flowering starts in June and lasts till the end of the autumn.
         The flowers are tubular (similar to the revolver flower). (Italiano’s Cases).
    Habitat:  This too common European plant has become naturalized in the North - eastern United States, where it flowers in June. It is said to be a sure indication that the soil is dry in all localities that it chooses as its habitat. (Information refers to Convo-a) (Millspaugh’s Medicinal Plants).
