yerba de burro (donkey’s herb, Dominican Republic);<br />

yerba de caimán (caiman’s herb); yerba de<br />

hicotea [hycotea, jicotea] (turtle herb, the jicotea<br />

is a freshwater turtle, Taino, Dominican Republic,<br />

Puerto Rico)<br />

Most of Polygonum is referred to as ‘‘smartweed.’’<br />

Diggs et al. (1999) cite a comment by Kirkpatrick<br />

(1992) suggesting that the name was derived from the<br />

tendency of the sap to ‘‘smart’’ (burn) when it touched<br />

the skin. However, historical data support a slight<br />

modification of that view. ‘‘Smartweed’’ was applied<br />

to P. hydropiper by 1787. In that year, W.H. Marshall,<br />

writing on the rural economy of Norfolk, said,<br />

‘‘Smartweed, biting and pale-flowered persicarias;<br />

arsmart.’’ Indeed, the OED lists ‘‘arsesmart’’ as the<br />

common name for ‘‘smartweed.’’ So, Kirkpatrick had<br />

the right idea, but the wrong part of the body.<br />

Several species have a peppery taste, like P.<br />

hydropiperoides and its namesake P. hydropiper (water<br />

pepper). Indeed, Dutch herbalist Rembert Dodoens<br />

simply called the second species Hydropiper in 1554,<br />

surely reflecting its use in seasoning food. Fernald<br />

et al. (1958) noted that application for it and several<br />

relatives. The practice is problematical because some<br />

people develop contact dermatitis from the plants<br />

(Foster and Duke 1990).<br />

There appear to be no records of people in the<br />

Americas using P. densiflorum, but Hawaiians use an<br />

infusion of the plants to purify the blood (Moerman<br />

1998). Perhaps that species is used like some of the<br />

others in the New World although there are no records<br />

to support that. In the Bahamas, the root of P.<br />

densiflorum is crushed and inhaled to relieve headache<br />

(Higgs 1969).<br />

The earliest association of Polygonum with Florida<br />

people was P. hydropiperoides in pre-Columbian<br />

Glades coprolites from Fort Center on Lake Okeechobee<br />

(Hogan 1978). Polygonum hydropiperoides<br />

contains tannins, rutin (3% in the leaves), quercitin,<br />

and kaempferol (Hocking 1997). It has been used to<br />

stop intestinal and uterine hemorrhage, for strangury<br />

(slow, painful urination), and as a stimulant. In Brazil,<br />

P. hydropiperoides is considered diuretic, and an<br />

emmenagogue, and used as a treatment for piles. It is<br />

used to promote conception in Mexico (Ford 1975,<br />

Hocking 1997, Vásquez and Jácome 1997).<br />

Among the Houma, a decoction of P. punctatum<br />

roots was used to treat pains and swelling in the legs<br />

and joints (Speck 1941). Farther north, the Ojibwa<br />

took a decoction of leaves and flowers for stomach<br />

pain, and the Iroquois made a compound medicine for<br />

‘‘loss of senses during menses’’ (Moerman 1998). The<br />

Tarahumara of northwestern Mexico used the plants<br />

as a fish poison (Pennington 1958). They bundled the<br />

plants, crushed them, and put them in large baskets,<br />

which they dipped into water until the water turned<br />

green. According to Pennington (1958), ‘‘fish rise to<br />

the surface almost immediately.’’ Tarahumara also<br />

added young leaves to their corn dish esquiate for a<br />

spicy flavor.<br />

In Hispaniola, P. punctatum and other plants in<br />

the genus are rubefacients when crushed; they are<br />

stimulant, astringent, diuretic, emmenagogue, anthelmintic,<br />

and antiarthritic. On that island, the species is<br />

used against urinary and gallbladder problems, and to<br />

treat hemorrhoids, intermittent fever, and malignant<br />

sores (Liogier 1974). Several of the common names<br />

mention dogs. Those are indications that the herb is<br />

wild, but perhaps also indicates that the plant has been<br />

used to treat mange (jiote, fromxiotl, Náhuatl) in dogs<br />

(Morton 1981).<br />

Europeans were familiar with Polygonum when<br />

they arrived in the New World. They had learned that<br />

the small seeds from weedy species like P. aviculare<br />

could be harvested and used, at least as a starvation<br />

diet (Fernald et al. 1958). Indigenous Americans also<br />

used P. erectum in the same way. Indeed, there is<br />

evidence they cultivated that species for food (Smith<br />

1992). More recently, the seeds of at least P. hydropiperoides<br />

have been promoted as a protein source<br />

(Boyd 1968, Boyd and McGinty 1981).<br />

Polyporus<br />

(The genus was named by E.M. Fries, 1794 /1878, from<br />

Greek poly, many, and Latin porus, small openings)<br />

false truffle (USA)<br />

okipen (earth tuber, Virginia Algonquian)<br />

turma (truffle, name used by Fontaneda [1575]<br />

1944)<br />

When Hernando Descalante Fontaneda was rescued<br />

from his captivity among the Calusas of southern<br />

Florida, he returned to Spain and wrote an account of<br />

his time among those people (Fontaneda [1575] 1944).<br />

One of the few ‘‘plants’’ he mentioned was a root eaten<br />

by the Floridians. In speaking of people who lived on<br />

the laguna de mayaimi (Lake Okeechobee), he wrote,<br />

‘‘y sobre esta laguna que corre por en medio de la tierra<br />

dentro tiene muchos pueblos aunque son de treynta i<br />

quarenta vso. y otros tantos lugares tienen pan de rraises<br />

ques la comida ordinaria la mar parte del tienpo, aunque<br />

por caso de la laguna que crese mucho que no alcansan<br />

estas rraises por estorbo de la mucha Agua y ansi dejan<br />

de comer Algun tienpo este pan pescado mucho y muy<br />

bueno, otras Rayses a manera de turmas de las de Aca<br />

duses.’’
