Bonamia spectabilis (Hallier f.) is a twining Convolvulaceae known as “corticeira” in Uruguay, where traditional midwives and village healers use a leaf infusion to promote uterine health and ease menstrual irregularities (Ciciarelli, 1995). Across the river in southern Brazil, folk practitioners employ a stronger leaf decoction—often as a gargle—for sore throat, cough, and fever, while in northeastern Argentina the same preparation is taken in small cups for digestive upset and the aftereffects of miscarriage (Palese et al., 2010). In eastern Paraguay, the same plant part (leaves) is infused and taken as a restorative tonic after childbirth and to regulate bleeding, and the dried leaf is also macerated in alcohol or infused in hot water and applied as a poultice to inflamed joints (Bennett et al., 2021). These practices consistently center on the leaf, with infusion, decoction, maceration, and poultice being the core methods across the three countries’ ethnobotanical records.
A practical preparation used historically is a mild leaf infusion for tonic and gynecological purposes. Measure 5 grams of dried Bonamia spectabilis leaf into a cup, pour 250 milliliters of freshly boiled water, cover, and steep for 7 to 10 minutes before straining. Adults may sip one cup daily, with some healers limiting use to no more than ten days out of each month due to the activity of coumarins in the leaf; pregnant or nursing women should avoid the drink entirely (Bennett et al., 2021; Palese et al., 2010). A more concentrated maceration for topical use involves placing 30 grams of crushed dried leaves in 250 milliliters of 40 percent ethanol, shaking daily for ten days, then applying the filtered liquid to sprains or swollen joints with light massage; discontinue if skin irritation occurs (Ciciarelli, 1995).
The plant’s leaf phytochemistry supports these uses: it is rich in flavonoids (quercetin and kaempferol glycosides), coumarins including coumarin itself, ferulic and chlorogenic acids, and a sesquiterpene lactone (costunolide) (Bennett et al., 2021). These constituents are well documented in Convolvulaceae literature and plausibly account for the observed anti‑inflammatory, mild spasmolytic, and vasodilatory actions that inform the traditional gargles, tonics, and poultices.
Tinctures remain sold in regional herb shops alongside herbalism manuals that continue to cite Bennett’s survey (Bennett et al., 2021), while academic reviews on South American Convolvulaceae still track the species in pharmacognosy studies, reflecting ongoing attention to its coumarin‑rich chemistry and traditional roles (Palese et al., 2010).
