Gynura procumbens - Sabungai, Leaves of Gods, Longevity Spinach

Polska wersja

PLANT PROFILE

Gynura procumbens is a vine, quite popular in South East Asia and some parts of Central Africa. It is highly esteemed for its medicinal and culinary values, but still mostly unknown outside those regions. As a herb it is famous for its antidiabetic, anticancer and hypotensive properties, but there are much more virtues of this plant. As for its pure culinary uses, it is often compared to spinach, with common names Longevity Spinach, Mollucan Spinach or Cholesterol Spinach. It is also called Leaves of Gods. Here are some common names in other languages : Sabungai, Kamangi (Tagalog), Paetumpung (Thailand), Sambung nyawa (which means Extending Live, - Indonesia), Deva raja, Akar sebiak, Kacham akar (Malaysia), Chi angkam (Cambodia), Kim That Tai, Cai Tieu Duong, Tiem Vinh (Vietnam), Man san qui cao, Lam fei yip, Bai bing ca, Ping wo ju sam qi (China).This plant have also many latin synonyms including Senecio cacaliaster, Cacalia cylindriflora and Crassocephalum latifolium, but none of them seems to be in use nowadays.
There is a lot of misinformation on internet and plant market in the Philippines, as Gynura procumbens is often called Ashitaba or Asitava. In fact the real Ashitaba is Angelica keiskei, and it is highly unrelated plant.
Gynura procumbens is very closely related to Gynura bicolor aka Okinawan Spinach, and sometimes mistaken with.

CULTIVATION AND HARVESTING

Sabungai is a perennial, climbing vine, growing wild on edges of tropical forests and bushes, meadows, near streams, or other wet but well drained soils, and semi-shady places. It like rich soils , and can quickly spread 6m in lenght. It also can grow on poor, bit dry soil and cope with full sun, but its growth will be slow. This plant is not hardy at all, and temperatures just below 5'C can damage it. Even though it is a vine, its stems are not really flexible, even when young, so with regular tips cutting it can sustain as a small bush. Gynura procumbens grows very fast, so if the plant is already strong and 0,5m big, it'll probably grow quicker then you'll be able to eat it. Pick the fresh young tips any time you want, preferably straight before eating. If you want to dry some leaves for tea, choose older leaves. It is more rich in bioactive compounds, and contain less water in its tissues than the young one, so it'll dry easier.

CULINARY USES

Young leaves and stems of Gynura procumbens are crunchy and succulent, but even older leaves are not hard, and it usually have more valuable content and less water. It can be used fresh in the same way as salad leaves, for sandwiches and salads, or turned into smoothie (squeezing and drinking, only pure juice out of it, is in my opinion waste of healthy, nutritious plant matter). It can also be boiled, blanched or steamed like spinach, or added to soups, stews or stir-fries. Dried or fresh, cutted leaves and stems, can be used for making herbal tea.

MEDICINAL USES

Fresh leaves of Gynura procumbens have long tradition of medicinal uses in South East Asia. It is a remedy for diabeties, hyperlipidemia, hypertension, cancer, fever, rashes, urinary infections, kidney problems, inflammations, allergies, herpes and viral infections, migraine, constipation, rheumatism and dsyntery. This plant is highly rich in antioxidant and antiinflamatory flavonoids and other phenols, and anticancer proteins - peroxidase. It also contain tannins, alkaloids, saponins, sterols and essential oils. Eating few leaves daily lowers blood sugar ( but not for people with normal sugar level ), blood pressure and cholesterol level. Sabungai leaves poultice is applied for rheumatism and muscle pains, ulcers, wounds and inflammations. There is report of 70 year old man that cured himself from prostate cancer by drinking gynura tea daily.
There are informations about traditional use of this herb as a abortifacient, in some parts of Asia, therefore it should be avoided by pregnant women.

It was used for this purpose by Aztec, who used it also as a glue and to make modeling figures. But today it is hard to find anywhere, this expensive, traditionally made, original chewing gum. While its commercial successors popular around whole world, are made mostly from synthetic rubber. Also wood from this tree is used commercially, it is very durable and good for furniture and tools production. Sapodilla is probably native to south Mexico, Belize and Guatemala, where it has been cultivated since ancient times. Mayan writings mention about milions of Zapotle trees growing on Mayan civilisation territory. And nowadays it is popular as a fruit tree in nearly whole tropical world and also in subtropical climate regions.
Manilkara zapota fruits have many different common names in different countries and languages : Sapodilla (English), Zapotilla (Spanish), Chico (Tagalog) - also Chikoo, Chickoo, Chikoo or Chiku, Chicosapote (Guatemala, Mexico, Hawaii), Naseberry (West Indies and some parts of India), Sapodilla Plum (India), Nispero (Mexico, Spanish speaking countries), Sapotilla, Sapote or Sapota ( Brasil), Briapfel (Germany), Sapotille (France), Zapota (Venezuela), Zapote (Cuba, Honduras, El Salvador), Baramasi (Bengal and Bihar, India), Sapeta (Orija), Mispel (Virgin Islands), Sabudheli (Maladives), Saos or Sawo (Indonesia), Lamoot (Thailand), Muy (Guatemala), Muyzapot (El Salvador), Sapojira (Japan), Kkom na mu (Korea), Gudalu (Nepal), Ya (Jucatan), Rata-Mi (Sri Lanka), Hong Xiem (Vietnam) - and these are just some of them. Sometimes synonym of this plant - Achras zapota can be still found in use.

CULTIVATION AND HARVESTING

Sapodilla is rather slow growing, long lived, tough tree, very dense, medium hight and evergreen. It is tropical plant that can easily adapt in not stictly tropical regions as well. Young plants are getting killed by temperatures below 0'C, but older plants can survive frosts to -4'C with only moderate damage. Manilkara zapota thrives in full sun, in rich, acidic, sandy, well drained soil, but will grow in poor soils as well. It tolerates well drought, heat, salinity, and is strongly wind resistant. Sapodilla is very fruit productive, it can yield fruits when it is 5 year old, nearly all year round, with one or two main crops. In India saline water is used for watering, to reduce vegetative growth and promote fruiting. Fruits matures afrter 4 to 8 months from polination. There are quite few varieties with different fruit sizes and shapes ( from 4cm round 'Pineras' to 8cm long, conical 'Ponderosa' ), which might be suitable for different conditions. These are usually propagated by marcotting, but it might be grown from cuttings and seeds as well. Sapodillas milky, gummy sap is gathered by cuttings on its tree trunk, then dried and usually cut into stripes for chewing.

CULINARY USES

There are different varieties of Sapodilla fruits, and of course taste may vary a bit according to different soil, weather and time of harvest or way of storage. I've been lucky to get these fruits frequently in England (it comes there from Dominican Republic) and now in Philippines, and it taste unlike anything else. Very sweet, soft flesh, inside thin but firm skin, reminds me a bit a taste of fully ripened pear with hint of vanilla and cinnamon. I've been eating many rare fruits in my life and nothing realy tastes like this delicious one. But there is big '' but '' - these fruits are very tender when ripe, so in order to reach markets on distant lands, it have to be picked fairly unripe. Then it is keeping in cold storage and sometimes laying for long time on stalks, being pressed by many hands, checking if it is soft yet. So at the end, if You'll be lucky to find this fruit far from region of origin. It will be not only quite expensive but half of it might be spoiled (with good looking skin but fermented pulp inside) or so unripe, that unable to get ripe even laying on the sun for long time.
Unripe, hard fruits are very tart and just slightly sweet, but the more ripe they are the more soft and sweet its flesh is. Chico can be eaten raw on its own or added to any kind of desserts, from fruit salads to ice creams and milk shakes. It is turned into jams, syrups, fried or fermented into wine. It also might be blended with egg custard and baked or added to pancake batter. In Indonesia young shoots are eaten raw, after washing sticky sap off or steamed with rice. Sapodillas dried sap called Chicle was chewed by Aztecs and Mayas to quench thirst, and was highly valued by European settlers for its subtle flavor and high sugar content.

It was a unique expierience. It has a very intense and hard to describe flavour, with strong bitterness. I chewed it a bit, swallowed, and drank a glass of water.
