Usos
Uses
It somewhat resembles certain types of heliconia. Its spicy fruit is edible and harvested in different countries such as Ecuador and Mexico. It also produces cooking oil, ink, and is used as a medicinal plant to treat nausea. The crude hexane extract from the leaves of this plant has been used to treat leishmaniasis.
Pigmento
Pigment
The huitillo yields a purple color after macerating ripe fruit’s skin. This plant offers a wide spectrum of possibilities because it produces a high-yielding pigment that easily binds to the different surfaces used. Exposure to heat is indispensable during the setting process. An intense indigo blue is the result of using only the skin. If lemon is added, the color turns purple-fuchsia, and if the pigment is mixed with white clay, the result is a pastel purple. When a fair amount of alum stone is applied, the result is a purple-royal blue shade.
