Calabaza was a ritual offering presented in honor of the dead during the month of Miccailhuitontli by the Aztecs and is still considered an appropriate addition to the altar during El Dia de Los Muertos celebration in Mexico in the form of calabaza en tacha (candied squash).
In addition to a delightful culinary treat, calabaza has been used medicinally to treat intestinal parasites, gastric disorders, obesity, diabetes, and nervios (nerves).
Cooked squash of any variety is good anytime to calm the nerves. If you’d like to find a way to incorporate more squash in your diet, horchata de semillas de calabaza is a refreshing beverage. Take 100 grams of squash seeds (pepitos) and 5 grams of hierbabuena fresca (fresh spearmint leaves). Add ¼ liter of milk and piloncillo (cone brown sugar) to taste. If you are using it medicinally, drink for three days in a row for stomach ailments.
There are five varieties of calabaza cultivated in Mexico today.
Cucurbita moschata (including butternut squash) is referred to by a variety of other names including calabaza de Castilla, calabaza de casco, calabaza de pellejo, calabaza cuaresmeña, calabaza caliente, calabaza de pepita menuda, támala, calabaza de camote, calabaza torpe, ayote, Xnuk kuum, Nujuch kuum, and Xmejen kuum (Maya). The seeds, roots, flowers, and squash from the cucurbita moschata variety are used to treat urinary tract infections and skin ailments. The extracted oil has antioxidant properties.
For parasites, one remedy calls for a concoction of 30 grams of aceite de ricino (castor oil) and a pinch of salt. This is paired with calabaza en tacha made from C. moschata without the skin served in ½ cup of milk.
Another parasite treatment consists of a handful of toasted or raw seeds known as pepitas also from the cucurbita moschata variety of calabaza (pumpkins) and a few hierbabuena (spearmint) leaves eaten on an empty stomach.
The flowers of the cucurbita pepo are eaten seasonally with blue or yellow corn tortillas, most often in quesadillas. To prepare the flowers, they are boiled and the water is discarded so that any toxins are eliminated. The flowers are also served as part of salads or stuffed with cheese. The roots, leaves, squash, and seeds of this variety are used to stimulate the appetite.
Cucurbita pepo is also known as calabaza de comer, calabaza de manteca, calabaza de carrizo, calabaza mediana, Tsol, Tsool, Tzol (Maya) tempranilla, and mensejo. The grated raw peel from the cucurbita pepo is applied to burns and hemorrhoids as it is effective in wound healing. This variety, from root to fruit, is used in several areas of Mexico to improve health in general. It has a pancreatic lipase inhibition effect.
Cucurbita argyrosperma is also known as calabaza caliente, calabaza de las aguas, calabaza pinta, calabaza de casco, calabaza criolla, calabaza pipiana, calabaza tapona, calabaza rayada, pipián, or calabaza guajolota. The seeds, flowers, young stems, and tender squash are eaten. The squash is made into a pulp and applied externally to treat skin ailments.
Cucurbita ficifolia is known as chilacayote, chilacayo, or chilaca. In Nahuatl, this variety was chilicayotli from the word tzilacayotli originally which translates to “smooth squash”. The young stems are eaten as a vegetable. When this squash is fully mature, it is fibrous and is used to make the sweet cabellos de ángel (angel’s hair) treat. Other candied squash made from this variety are dulce de alcayota, cayote en hebras, mermelada de calabaza, mazamorra de calabaza.
In Chiapas, the seeds are toasted and set in honey to make palanquetas (a candy bar). C. ficifolia has a marked hypoglycemic effect. It also has antioxidant and anti-inflammatory properties. Extract from C. ficifolia has been shown to be promising in the treatment of obesity.
Cucurbita maxima is also known as zapallo. Its seeds are the snack pepita rusa (Russian pumpkin seeds), eaten salted and toasted. This variety includes the red or orange pumpkin most people associate with Halloween. It is native to South America. In Chiapas, this variety is called malayota because it resembles tamale dough when pulped.
C. maxima has been shown to quickly decrease high blood glucose levels. C. maxima seed oil is useful in treating an overactive bladder. Ayo-nelhuatl (cucurbita maxima) root is mentioned in Libellus de Medicinalibus Indorum Herbis as part of a concoction used as an after-birth vaginal wash.
These five are the most commonly cultivated calabazas found in Mexico. However, there are other wild calabazas that are used medicinally as well.
Cucurbita foetidissima (Buffalo Gourd) is a wild calabaza whose sour fruit is used medicinally after being cooked. The seed sprouts and roots are toxic and should never be ingested. The leaves and roots are used medicinally in Chihuahua. In other states, the roots are used to make soap because of its saponin content.
This variety is also known as calabacilla amarga, cohombro, hierba de la víbora, calabaza amargosa, calabacilla loca, calabacilla silvestre, calabaza de burro, chili coyote, calabaza hedionda, calabaza silvestre, calabaza del diablo, calabacilla de burro, Cua-cua (Chontal), chichic-amole and guelto-lana (Zapotec).
Apodanthera undulata (AKA calabaza hedionda or melon loco) is made into a pulp and used topically in the state of Guanajuato. The seeds are used to stimulate appetite in Jalisco and Zacatecas where it is known as calabaza amarga or calabaza loca.
In addition to the medicinal applications already mentioned, all calabazas varieties have antifungal and antibacterial properties. One more interesting cucurbita is the Cayaponia tayuya. The roots of this squash, native to the Amazon, have been useful in treating rheumatoid arthritis and also been proven helpful in the treatment of Epstein-Barr and skin tumors.
It just goes to show that a plant we may overlook may be full of beneficial properties.
