PLANT PROFILE
Abelmoschus manihot is a perennial shrub from Hibiscus tribe of Malvaceae family. It probably originates from tropical and subtropical areas of southern and eastern parts of China, and from there it was spread to north of India and Southeast Asia. And nowadays it is cultivated and often also grows wild in the South Asia region from India and Sri Lanka, through Myanmar, Thajland, Indonesia, the Philippines to Melanesia, Polynesia and northern Australia. It was also introduced in some regions of Africa and South America.
It is commonly cultivated as a leafy vegetable, but often also for its medicinal use and sometimes as an ornamental plant, as its big yellow flowers has a lot of charm. It is highly polymorphic species, as its leaves form vary from slightly to deeply cutted palmate or can even have a thin spearhead-like shape. And even on one plant there might be signifficant differences in shape of the leaves. A huge number of differently looking cultivars of Abelmoschus manihot, is mainly due to the fact that this species domesticated plants easily get crosspolinated by wild forms of A. manihot, as well as with other species from genus Abelmoschus. To which among few other belongs Abelmoschus esculentus and Abelmoschus caillei species, which seedpods called Okra are popular vegetable in many regions of the world.
Abelmoschus manihot popularity is much lesser, as it is little known outside of S-E Asia and Oceania. And even there it stays unknown or little known in many parts of the regions. But in some communities of Indonesia, Papua New Guinea, Vanuatu, Samoa and Fiji, it is one of the most commonly used leafy vegetables. Grown in private vegetable gardens or gathered from wild, but sometimes also cultivated on plantations, and often sold on local markets, in form of bundles of whole stems with leaves. Plantators in Fiji even export fresh A. manihot leaves to Canada and frozen to New Zealand, Australia and USA, where it is much appreciated mostly by migrants from Pacific islands, longing for their traditional food ingredients.
Although medicinal properties of Abelmoschus manihot are lesser known than its highly nutritional value. In many communities it it is highly esteemed as a medicinal herb, and its leaves are consumed as a remedy for many diseases, from stomach problems, urinary ailments to fever, headache and tumors. In China the flowers of Abelmoschus manihot has been used for centuries to treat even most serious kidneys problems. It was described in two oldest books of classical Chinese medicine, namely Jia You Ben Cao (mid-11th century) and Ben Cao Gang Mu (1578), and officially listed in 2015 edition of the Chinese Pharmacopoeia.
Abelmoschus manihot was also used in China for centuries as an ingredient in paper making. Nowadays the plant's musilage is still used in Japan in production of special paper called Washi, and in Korea traditional paper called Hanji.
Here are some of the common names used for this plant : Aibika, Aigiri, Gogae, Kabul (Papua New Guinea), Gedi, Degi, Sarolo (Indonesia), Jungli Bhindi (Hindi), Raan Bhendi (Marathi), Usipak (Assamese), Kantalo Bhende (Gujarati), Phuttu Bhaji (Chhattisgarhi), Sweet Hibiscus, Edible Hibiscus, Manihot Mallow, Sunset Hibiscus, Yellow Hibiscus, Lettuce Tree, Queensland Greens (English), Pele (Samoa, Tonga, Tuvalu, Cook Islands), Bele, Vauvau, Momoke (Fiji), Nuk, Barmai, Kwere (Vanuatu), Slippery Cabbage, Island Cabbage, Pacific Cabbage, Nambelle, Neka, Lema, Gole (Solomon Islands), Te Nambere (Kiribati), Naonit (New Caledonia), Lagikuway, Barakue, Glikway (the Philippines), Paw Fai (Thailand), Bonde, Koto (Sierra Leone), Gbamafetri (Ghana), Tororo-aoi, Kusadamo (Japanese), Dakpul (Korean), Somaradza (Tibetan) ; Chinese names: flowers - Huang Shu Kui Hua, seeds - Huang Shu Kui Zi, leaves - Huang Shu Kui Ye, stem or stem bark - Huang Shu Kui Jing, roots - Huang Shu Kui Gen. And you will find impressive extended list of A. manihot verncular names here.
Abelmoschus manihot in the past was also known under its botanical synonyms like : Hibiscus manihot, Hibiscus palmatus, Bamia manihot, Bamia magnifica and Erebennus manihot, to name just a few.
And some botanists recognise varieties of this plant like : dissecta, megaspermus, platidactylis, timorensis, pungens, genuinus, or subspecies : caillei, tetraphyllus. But other says that Abelmoschus caillei is probably hybrid of Abelmoschus manihot and Abelmoschus esculentus, or endemic African species.
And in my and many other scientists opinion Abelmoschus tetraphyllus is a seperate species, and the line between it and A. manihot, should be that all the disputed manihot-like specimens with any kinds of micro-hairs should be classified as tetraphyllus, while only those with glabrous leaves and stems should be recognised as a real A. manihot. That means consider A. manihot as a domisticated form of wild, hairy A. tetraphyllus, that evolved over centuries of selective cultivation of specimens with non-hairy and more juicy leaves, in order to acheive better vegetable type.
But at the present many if not the most of authors are stating that Abelmoschus manihot leaves and stems are covered with short hispid or prickly hairs.
CULTIVATION AND HARVESTING Abelmoschus manihot is a perrenial shrub, that when young is more of a robust herbaceus plant nature, as only its old stems become fully woody, while young one are quite soft and succulent. It has erect stems, and can reach height of up to 5m, and width of around 3m. In its wild state it can be found mostly in valleys and wet grasslands but also in wastelands and humid rocky hillsides. And it is commonly planted in vegetable gardens in pacific islands villages. It often grows as just an annual plant either due to climate conditions, like extreeme seasonal draughts or cold winters or because of cultivation manner. In temperate climates with mild frosts A. manihot dies back to the ground but can grow back from the underground parts.
Aibika prefers humid tropical climate, sandy loam and clay loam soil with fair amount of compost, pH between 5 and 7, and sunny position. And in those conditions it can have rapid growth of one meter per month in young plants. The growth of new stems and leaves, its number and size is lesser near and during flowering period, and also decline with plant's age. And for that reason A. manihot is cultivated mainly as an annual plant, as the old plants are removed and replaced with young ones, which are more leaf productive. Its propagation is quick and easy, as its woody and half-woody cuttings are growing roots very fast.
It can be also grown from the seeds, but the seedlings grow initially much slower than young plants from cuttings. Cuttings cultivation method also accertain you that your young plants will have all the characteristics of the mother plant. As cultivars of Abelmoschus manihot easily crosspolinate with wild forms of A. manihot, as well as with other species of Abelmoschus genus. This hybridisation and common occurance of mutations cause huge variation in morphology of this species. Its leaves shape can be anything from slightly to deeply cutted palmate, and also cordate or spear-like, while its size can be from a fist size to size of a big plate.
The leaves color can be from light to dark green or reddish, young stems and leaf petioles are often red or purplish. The leaves look can be even significantly different within the one plant, as it is often changing with weather conditions or growth stage, it is usually smaller in size in older plants and during the flowering period. The flowering of Abelmoschus manihot generally occurs during dry, summer months, but of course vary due to region, for example in China it is during August to October, in Fiji June to November, while in the Philippines it is December to March. The flowers are usually yellow with dark purple centre, but it can also be white with purple center.
This plant is said to grow best in lowlands at altitudes to 800 m, but I have grew mine in the Philippines at elevation of 1400 m with good results, and it is noted to be cultivated even at heights of 2000 m. There is a huge number of cultivars of Abelmoschus manihot and some might be better adapted to particular conditions than other, for example : narrow-leaved Aibika varieties may be more drought tolerant than round-leaved forms.
A. manihot does not require much maintenance and it is usually cultivated in a mixed-cropping system. It is commonly intercropped with low growing vegetables, root crops and banana. It is highly salt tolernt plant, although extensive salinity is slowing its growth. Its growth can be also slowed by deficiency of water or waterlogging in soil. But the plant can withstand seasonal droughts, and is said to tolerate alkalinity and micronutrients deficiencies.
With enough watering A. manihot can produce continous abundance of its juicy leaves all year round. The cuttings start to grow shoots after about two weeks and the first harvest is taken usually after 3 months. Since then it can be harvested weekly (stems tops) or even daily (separate leaves) for year or two, before the plants start to be less leaf productive. Seperate leaves, tender shoots or whole longer stems tops with leaves can be harvested. But in case of harvesting only the leaves, sporadic prunning have to be done to curb the height of the bush and encourage better branching, which cause better leaf production.
Unfortunatelly humans are not the only animals that like tasty, nutritious leaves of Aibika, pests like grasshoppers, caterpillars and aphids, also loves it. The other threats are : Aibika Jassid (Amrasca devastans), Shot-hole Beetle (Nisotra basselae), Green Coconut Bug (Amblypelta cocophaga), Spherical Mealybug (Nipaecoccus viridis), Red Cotton Bug (Dysdercus cingulatus), Red Spider Mite (Tetranychus urticae), Oribius Weevils (Oribius species) and White Fly (Hemiptera species). The plants can be also damaged by Black Shank (Phytophthora nicotianae), Myrothecium roridum and other types of fungal diseases, and viruses like Hibiscus Chlorotic Ringspot Virus (HCRSV). You can find more details about Abelmoschus manihot's pests and diseases and its prevention here.
Aibika leaves wilt easily, so for longer storage it is better to harvest leaves with the whole stem tops, and seperate the leaves from those stems just before the use. Seperate succulent shoot tips with very young, underdeveloped leaves also storage well. The mature leaves separately are best to be stored in plastic ventilated bags or containers in cool temperatures, it can be also wrapped in bababa leaves and occasionally sprinkled with water for better freshness. The whole stems can be held in buckets or other containers with water, so that the buttoms of the stems would be immersed in water.
CULINARY USES Abelmoschus manihot leaves are one of the most important leafy vegetables for many communities in Indonesia, Papua New Guinea and Melanesia, where many people consumes it daily. The leaves has soft texture and are juicy, mucilaginous and mild in taste. Which makes it a universal vegetable that combines well with any dish, and is great for salads and sandwiches. The very young immature leaves and stems tips are quite crispy, while older leaves can be a bit tougher and contain more mucilage. It is eaten raw, boiled in water or coconut milk, steamed, fried in vegetable oil or roasted on stone ovens.
In Fiji, Vanuatu and Tonga, Aibika leaves are much loved served like spinach. It is usually boiled for not longer than five minutes, and served hot with butter and lemon juice or coconut cream.
In Indonesia the leaves are essential ingredient for cooking porridge as a special gourmet food among the North Sulawesi cuisine, because the mucilage it contain enables the porridge to have a special viscosity. It is also commonly added to thicken soups and stews.
Aibika leaves and tops are great for making deep-fried batter snacks, like Indian Pakora.
The tender young leaves are low in fiber and rich in vitamins, which makes it excellent first food for infants when mashed together with root vegetables. While old leaves are good source of dietary fiber, which makes it usefull help in cases of chronic constipation.
Nutritious value of Abelmoschus manihot is much better than those of many popular leafy vegetables. For boiling Aibika a relatively small volume of water should be used, as some minerals, especially potassium, magnesium, zinc, iron and calcium are lost in the water. Therefore it is good to consume that water as a soup. Serving Aibika leaves with coconut cream, is said to increase the uptake of beta-carotene and conversion to vitamin A.
Abelmoschus manihot leaves contain high level of protein (18 - 24% of dry weight) and polysaccharides. It contains the essential amino acids : isoleucine, leucine, lysine, methionine, phenylalanine, threonine, valine and histidine. And is rich in vitamins A and C, riboflavin, thiamine, calcium, magnesium, iron, zinc, copper, potassium, manganese, phosphorus, sulphur and carotenoids ; more details, and here.
Aibika flower buds can be also eaten raw or cooked, and the fresh flowers was commonly eaten as a vegetable in old days in China. But unlike Okra, Aibika fruits are usually not smooth but covered with short bristle hairs, and therefore it is rarely eaten (but the anoying hairs can be scrabed off and Aibika fruits can be boiled just like Okra).
Despite that it is a heighly nutritious vegetable, Aibika should not be consumed by pregnant women, as some native tribes in Asia use it to induce abortion.
MEDICINAL USES Abelmoschus manihot was used as a medicinal plant for centuries. The oldest written record of its use as a healing herb comes from Zhou Hou bei Ji Fang ( A Handbook of Prescriptions for Emergencies ), written in 340 by Chinese physician Ge Hong. And it was later described in Chinese Medicine classics like Jia You Ben Cao (mid-11th century) and Ben Cao Gang Mu (1578). Chinese high regard for this plant's medicinal value, esspecially of its flowers, can be well seen, as they have listed it in 2015 edition of the Chinese Pharmacopoeia. Medicinal use of A. manihot has also long tradition and strong importance in some regions of India, Indonesia, Papua New Guinea, Fiji, Vanuatu and in other countries in South-east Asia, Melanesia and Polynesia (There are also reports of use of A. manihot as a medicine in some countries of Central and West Africa, although it might actually relate to use of Abelmoschus caillei). But while in China the plant's extracts are used also in clinical treatment by orthodox medicine doctors, in other countries this herb is only utilized by folk healers and traditional medicine practitioners.
Although, in the last decade interest of academics in medicinal potential of Abelmoschus manihot has risen, which resulted in many reaserches on the plants chemical constituents and its pharmacological actions (with the leaders in number of researches being China, India and Indonesia). And that has added to better understanding of Aibika's healing powers.
Traditionally all parts of this plant are used as a medicinal herb. Different parts of Aibika are commonly used as a mutual substitutes in treatment of many diseases, especially the leaves and flowers. But despite possesing many of the same medicinal properties, different parts of A. manihot might have different efectiveness in therapy of particular ailments.
Mucilage extracted from Aibika can be used in the same way like Okra mucilage, as a plasma replacement or blood volume expander.
