Kalmia latifolia, Mountain Laurel
This member of the Ericaceae family is not much used anymore due to its toxicity. According to Plants for A Future:
Mountain laurel is a very poisonous narcotic plant the leaves of which were at one time used by some native North American Indian tribes in order to commit suicide. Because of its toxicity, it is a remedy that is seldom used in modern herbalism, but the leaves have been used externally in herbal medicine and are a good remedy for many skin diseases and inflammation. The leaves are analgesic, astringent, disinfectant, narcotic, salve and sedative. An infusion of the leaves is used as a disinfectant wash and liniment to treat pain, scratches, rheumatism, inflammations and to get rid of body parasites. Used internally, the leaves have a splendid effect in the treatment of active haemorrhages, diarrhoea and flux. They are also used in the treatment of syphilis, inflammatory fevers, neuralgia, paralytic conditions, tinnitus and angina. The leaves should be used with great caution however, and only under the guidance of a qualified practitioner. Excess doses cause vertigo, headache, loss of sight, salivation, thirst, nausea, palpitations, slow pulse and difficulty in breathing.
Mrs. Grieves wrote similarly of Mountain Laurel:
A beautiful evergreen shrub from 4 to 20 feet. When in full flower it forms dense thickets, the stems are always crooked, the bark rough. It was called Kalmia by Linnaeus in honour of Peter Kalm, a Swedish professor. The hard wood is used in the manufacture of various useful articles. Leaves ovate, lanceolate, acute on each end, on petioles 2 to 3 inches long. Flowers numerous, delicately tinted a lovely shade of pink; these are very showy, clammy, interminal, viscid, pubescent, simple or compound heads, branches opposite, flowering in June and July. The flowers yield a honey said to be deleterious. The leaves, shoots and berries are dangerous to cattle, and when eaten by Canadian pheasants communicate the poison to those who feed on the birds. The fruit is a dry capsule, seeds minute and numerous.
Leaves possess narcotic poisoning properties and contain tannic acid, gum, fatty matter, chlorophyll, a substance resembling mannite, wax extractive, albumen, an acrid principle, Aglucosidearbutin, yellow calcium iron.
Medicinal Action and Uses---Indians are said to use the expressed juice of the leaves or a strong decoction of them to commit suicide. The leaves are the official part; powdered leaves are used as a local remedy in some forms of skin diseases, and are a most efficient agent in syphilis, fevers, jaundice, neuralgia and inflammation, but great care should be exercised in their use. Whisky is the best antidote to poisoning from this plant. An ointment for skin diseases is made by stewing the leaves in pure lard in an earthenware vessel in a hot oven. Taken internally it is a sedative and astringent in active haemorrhages, diarrhoea and flux. It has a splendid effect and will be found useful in overcoming obstinate chronic irritation of the mucous surface. In the lower animals an injection produces great salivation, lachrymation, emesis, convulsions and later paralysis of the extremities and laboured respiration. It is supposed, but not proved, that the poisonous principle of this plant is Andromedotoxin.
Preparations and Dosages---A saturated tincture of the leaves taken when plant is in flower, is the best form of administration, given in doses of 10 to 20 drops every two or three hours. Decoction, 1/2 to 1 fluid ounce of powdered leaves from 10 to 30 grains. Salve made from juice of the plant is an efficient local application for rheumatism.
King's American Dispensatory, 1898 tells us:
Action, Medical Uses, and Dosage.—In immoderate doses, sheep laurel is a poisonous narcotic, producing the symptoms above named, with diminished circulation. In medicinal doses, it is antisyphilitic, sedative to the heart, and somewhat astringent. Internally, either in powder, decoction, or tincture, it is an efficient remedy in primary or secondary syphilis, and will likewise be found invaluable in febrile and inflammatory diseases and hypertrophy of the heart, allaying all febrile and inflammatory action, and lessening the action of the heart. In active hemorrhages, diarrhoea, and flux, it has been employed with excellent effect, and will be found useful in overcoming obstinate chronic irritation of mucous surfaces. I have extensively used this agent, and regard it as one of our most efficient agents in syphilis; and have likewise found it very valuable in inflammatory fevers, jaundice, and ophthalmic neuralgia and inflammation. The remedy must always be used with prudence; and should any of the above mentioned symptoms appear, the dose must be diminished, or its use suspended for a few days. In cases of poisoning by this article, stimulants, as brandy, whiskey, etc., must be given, with counter-irritation to the spine and extremities. Sheep poisoned by eating the leaves, have been saved by administering 1 or 2 gills of whiskey to them (King). Scudder (Spec. Med.), states that he has employed it with marked advantage in secondary syphilis and atonic chronic inflammations. For the treatment of aching pains in the muscles of the face, muscular rheumatism with shifting pains, and in the early stage of rheumatism of the heart, success has been claimed for this drug, the specific medicine being used in from 1 to 5-drop doses. Bright's disease (?) is asserted to have been benefited by its use. Pain in the back during the menstrual period, and pain upon moving the eyes are said to be relieved by kalmia. Externally, the fresh leaves stewed in lard, or the dried leaves in powder mixed with lard to form an ointment, are said to be beneficial in tinea capitis, psora, and other cutaneous affections. "Some time since I treated a case of syphilis of five weeks' standing, which had not received any kind of treatment during that period. The patient, at the time I first saw him, had several chancres, the surface of the body and head was covered with small red pimples, elevated above a jaundiced skin, and he was in a very debilitated condition. I administered a saturated tincture of the leaves of kalmia, and touched the chancres with a tincture of chloride of iron, and effected a cure in 4 weeks, removing the jaundice at the same time" (King). The saturated tincture of the leaves or specific kalmia, are the best forms of administration; they may be given in doses of from 10 to 20 drops every 2 or 3 hours; the decoction may be given in doses of from ½ to 1 fluid ounce; and of the powdered leaves, from 10 to 30 grains. For acute disorders, particularly affections of the heart, from 5 to 20 drops of specific kalmia may be added to 4 fluid ounces of water, and the dilution administered in teaspoonful doses every hour. A salve made of the juice of the plant, forms an efficient local application for rheumatism. This remedy was a great favorite with Prof. King, especially for troubles depending primarily upon syphilitic infection.
Specific Indications and Uses.—Syphilis with excitation of the heart and circulation; rheumatism with shifting pains; cardiac excitation; cardiac palpitation excited reflexly from gastro-intestinal irritation; pain upon movement of the eyes.
Lagerstroemia indica, Crape-myrtle
Crape Myrtle is probably the most widely planted naturalized ornamental tree/shrub in my region. There is even an annual Crape Myrtle Festival in Scotland Neck, NC. I imagine it would surprise many native residents to find out that Crape Myrtle is not a native tree!
Plants for A Future states:
Medicinal use of Crepe Myrtle: The stem bark is febrifuge, stimulant and styptic. The bark, flowers and leaves are considered to be hydrogogue and a drastic purgative. A paste of the flowers is applied externally to cuts and wounds. The root is astringent, detoxicant and diuretic. A decoction of the flowers is used in the treatment of colds.
