Lippia nodiflora, Rich. (Verbena nodiflora, L.; V. capitata, Blanco.)
Nom. Vulg.—Tsatsatsatsahan, Chachachachahan, Tag.
Uses.—The Filipinos drink an infusion of the leaves in place of tea, the long Tagalog name meaning “resembling tea.” In India they drink the hot infusion to aid digestion. In some places the decoction of the leaves is given internally as an emollient and diuretic for gonorrhœa.
Botanical Description.—A small plant with creeping stem taking root where it touches the ground, obscurely angular, covered with short down. Leaves opposite, smooth, clasping the stem, inversely ovate, serrate only above, slightly downy. Flowers white, slightly purplish, axillary on a common peduncle, in a rough conical head. Corolla somewhat bowed, funnel-form, gaping, throat narrow, limb 4-lobed, one lobe shorter than the rest. Stamens 4, 2 longer. Filament almost wanting. Anthers 4, fertile. Ovary superior, style very short. Stigma semi-globose. Fruit, 2 seeds covered by the pellicle of the ovary.
Habitat.—Very common in the rice fields.
Tectona grandis, L.
Nom. Vulg.—Teca, Sp.; Tikla, Tag.; Dalondón, Yate, Kalayati, Vis.; Teak Tree, Eng.
Uses.—The powdered wood made into a paste with water is undoubtedly a useful application in acute dermatitis, especially that due to contact with the caustic oleo-resin of the cashew nut (Anacardium). A decoction of the powder gives good results as a gargle for aphthæ, gingivitis, and other inflammations within the buccal cavity. In India they give internally 6–12 grams as a vermifuge, and for dyspepsia with “heartburn.”
The flowers are diuretic according to Endlicher; the bark is astringent; the leaves and the seeds are purgative, the latter yielding an oil which they use in India to stimulate the growth of the hair. Gibson considers the seeds diuretic and quotes two cases where abundant diuresis immediately followed by the application of a poultice of the bruised seeds over the pubis. In Concan they make a sort of extract from the wood and apply it to the yoke sores of the cattle to prevent the growth of maggots. This disinfectant action marks the plant as worthy of further experiment.
Rumphius is authority for the statement that the infusion of the leaves is used in cholera. The Chinese make vessels of the wood to preserve their drinking water at sea; the first and second waters are bitter and are thrown away, but after that the water has no disagreeable taste and is said to aid digestion.
