lignum vitae / Guayacán
Scientific Name: Guaiacum officinale
Origin: South America
Botanical Family: Bignoniaceae
Guayacán is a critically endangered Caribbean evergreen tree known for its medicinal properties and flavoring uses.
Brief History and Description
Guayacán is a beautiful tree native to the American Caribbean. It is an evergreen tree that reaches a height of 5 to 20 meters and has a round crown that provides pleasant shade. Flowers are light blue or purple in color. Fruits are heart-shaped, each containing several black seeds.
Culinary Usage and Nutritional Properties
Guayacán extracts show good antioxidant activity and may be suitable for development as medicine and food supplements. Its bark, flowers, and leaves are reported to mainly contain saponins, such as galanin and guaiacum.
Tea is produced by boiling the leaves, and it is also made from its flowers. Guaiac wood is used as a flavoring in foods and edible oils and fats, and it is also used to flavor chewing gum and cakes.
Economic and Environmental aspects
Its dense canopy provides excellent shade, making it perfect for open areas exposed to high solar radiation. Its flowers produce nectar that attracts several species of honeybees.
Regrettably, the wild populations of this species are very reduced due to the exploitation of wood to which it was subjected for several years, which is why it is currently listed as critically endangered by the International Union for the Conservation of Nature (UICN).
A medicinal resin called "guaiacol" is secreted from its skin, and this resin, which either spontaneously oozes from the damaged tree or is artificially extracted from the wood, is commercialized for medicinal purposes.
This plant's primary importance lies in its wood, shade, and aesthetic appeal.
