Goat's Foot Morning Glory of the Yucatan
Monday, March 2, 2009 at 3:43PM During my visit to the Yucatan in early February, I came across these huge patches of vines, large round leaves, and morning glory-type flowers. I was walking the beach close to my friend’s house in Puerto Morelos and noticed these plants were growing everywhere! In fact, just about everywhere we went that was close to the beach had these large tightly knit mats of morning glories.
I took a few photos and compared them to research I did on the Internet. I was on the right track, it was a species of Morning glory, called the Goat’s Foot.
Ipomoea pes-caprae, the genus Ipomoea being the main morning-glory genus, and "pes-caprae" being Latin for "goat's-foot." It’s a common tropical creeping vine found on the upper parts of beaches and is a widely distributed salt tolerant plant, providing cover and protection of the beach sand.
Its seeds float and are unaffected by salt water. This species can be found on the sandy shores of tropical Atlantic, Pacific, Indian, and Caribbean, and also is common on the sand dunes of Australia’s north coast and the entire Queensland coastline. It’s a sand stabilizer and is one of the first plants to grow in the sand dunes. It sprawls out from a woody rootstock, spreading seaward with long runners and thrives under conditions of sand blast and salt spray.
This vigorous plant can grow to 16 feet long and the sun does not shrivel its leathery thick leaves which can be from 2 to 4 inches in length. It’s used extensively to stabilize large areas of sand, preventing erosion from wind and waves. It proves to work better than most technological solutions!
The funnel shaped, mauve or dusty pink morning glory flowers have five points and will bloom singly or a few in a cluster. Like most Morning Glories, they tend to open up in the morning. I found some in bloom while I was in the Yucatan early February.
It is found growing wild and one can easily take a cutting and simply stick it in the sand. It roots very quickly. The picture on the left shows it thriving on beach sand. It disperses seeds which are carried in and out by the tides and distributed to other beaches.
It is related to the sweet potato, kang kong and morning glory. It is known as salsa-da-praia in Brazilian folk medicine and has been used for inflammation and gastrointestinal disorders.
Plant roots and leaves were used as a famine food and were used in preparations for lung ailments, sprains and as a blood cleanser. The young leaf buds were eaten by pregnant women and the stems were cut into short lengths and applied to the breasts of women who had just given birth. The milky white sap was used to stimulate the flow of milk.
The vines had many practical uses. They were used in home construction, weaving baskets, and making fishnets. The vines were used to drive fish into waiting nets and sometimes were stripped and tied together to form cables for tying ships or as guide ropes to lower people deep into the sea.
Because of the seeds’ hallucinogenic properties, the Aztecs used the Morning Glory seeds to communicate with the Sun Gods as a ritual. Natives in Mexico (Oaxaca region) believe that the deity lives within the seeds.
Ancient Mesoamerican civilizations used the morning glory species Ipomoea alba to convert the latex from the Castilla elastica tree and also the guayule plant to produce bouncing rubber balls. The sulfur in the morning glory's juice served to vulcanize the rubber.
According to Wee Yeow Chin, the juice squeezed from the plant is used in Malaysia to treat fish stings. The leaves are used in Indonesia to hasten the bursting of boils; sap from the young leaves are boiled in coconut juice and used to treat sores and ulcers; and the seeds chewed with areca nut, soothe abdominal pains and cramps. In the Philippines, the boiled leaves are used to treat rheumatism.
I was impressed with this species, thriving in such harsh conditions. From what I've learned in my herbalism studies, sometimes the plants that survive the worst of conditions, often are the most potent healers.
