Nelumbo nucifera
FAMILY: Nelumbonaceae (Nymphaeaceae)
SYNONYMS: N. komarovii, N. nucifera var. macrorhizomata, Nelumbium speciosum, Nymphaea nelumbo, Indian lotus, sacred lotus, pink lotus, bean of India, kamala and padma (Sanskrit).
GENERAL DESCRIPTION: The sacred lotus is a perennial aquatic plant with rhizomes that grow in the mud at the bottom of shallow ponds, lakes and marshes. Its large leaves, which rise above the water surface, can be up to 60 cm in diameter, with a 3-metre horizontal spread, while the showy flowers can be up to 20 cm in diameter. The beautiful pink, fragrant flowers are solitary, borne at or above the leaf level, with a brilliant yellow centre and white sepals. The fruits form a conical pod, with seeds contained in holes in the pod.
DISTRIBUTION: Native to Greater India, the sacred lotus now occurs in the wild in warm-temperate to tropical regions throughout Asia, the Middle East and tropical Australia. It is common in China, Japan, Iran, Bhutan, India, Indonesia (Java), Korea, Malaysia, Nepal, New Guinea, Pakistan, Philippines, Russia (Far East), Sri Lanka, Thailand, Vietnam and north-west Australia. Introduced to Europe in 1787 as a ‘stove house water lily’ by Joseph Banks, today it is cultivated as an ornamental plant worldwide.
OTHER SPECIES: The family Nelumbonaceae has two important genera having aquatic species with attractive flowers i.e. the lotus, Nelumbo and water lily, Nymphea. The genus Nelumbo has only two species, N. nucifera (Indian or sacred lotus) and N. lutea (American lotus or yellow lotus).
The Egyptian blue lotus (Nymphaea caerulea) and the white sacred lotus of Egypt (Nymphaea lotus) are both members of the water lily family. These water lilies are indigenous to Egypt and their flowers are often depicted in Egypt’s ancient art. Remains of both blue and white water lily petals were found in the burial tomb of Ramesses II and sprinkled on the mummified body of Tutankhamun. The blue lotus is also mentioned in numerous Egyptian historical texts, mainly for its aphrodisiac, narcotic and euphoric properties. Both species are still cultivated in Egypt as well as in India and Indonesia today and are both used to produce absolutes, although these are rare and costly. Egyptians refer to both these flowers as ‘lotus’ so these two species are often confused with the ‘true’ lotus species.
HERBAL/FOLK TRADITION: Nelumbo nucifera has been in cultivation for more than 3,000 years, and has been grown not only for its cultural and ornamental value, but also for medicinal uses and for its edible seeds and rhizomes. In China, Japan and India, for example, the rhizomes are roasted, pickled, candied or sliced and fried as chips. A paste made from the nutlets is used as a filling in mooncakes (traditional Chinese pastries). The young leaves, leaf stalks and flowers are eaten as vegetables in India. The petals of the flower are used as a wrap for foods in Asia and the rhizome is a common ingredient in soups and stir-fries.
The sacred lotus has also been used as a medicinal herb for generations in Asia and its uses in contemporary medicine are virtually unchanged. Many parts of the plant are used: the leaf juices are used for diarrhoea and sunstroke when mixed with licorice; the flower is used for abdominal cramps, bloody discharges, bleeding gastric ulcers, excessive menstruation and post-partum haemorrhage; the flower stamens are used in urinary frequency, premature ejaculation and uterine bleeding; the fruit is used for agitation and fever; the seed has been shown to lower cholesterol levels and to relax the smooth muscle of the uterus and is used for poor digestion, chronic diarrhoea, insomnia, and palpitations. Various parts of the flower, including the petals are used for diarrhoea, cholera, liver conditions, bronchitis, skin eruptions, snake bites, and scorpion stings. The dried flowers are prepared into a syrup to treat coughs and the stamens are dried and made into a fragrant herbal tea. Practitioners of Ayurvedic medicine use lotus flowers for their soothing, cooling properties and they are often employed in skin care to improve the complexion. Oils from the lotus flower are said to have a calming influence on those suffering from fear, anxiety, insomnia or tremors, according to the principles of Ayurveda. A recent study has shown that oil extracted from the lotus flower might be effective in preventing greying hair.
Several bioactive compounds have been derived from these various plant parts belonging to different chemical groups, including alkaloids, flavonoids and glycosides which all have their own therapeutic impact. Both Nelumbo nucifera and Nymphaea caerulea contain the alkaloids nuciferine and aporphine, which have a sedative effect; studies using isolated neferine (found only in N. nucifera), indicates it has potent antidepressant and sedative properties. Sacred lotus is also nutritious, containing vitamins B and C, protein, fat, carbohydrate, starch, moisture, sucrose, calcium, phosphorus, iron and ascorbic acid.
The lotus is of great significance to many Asian cultures, and in particular to the Eastern religions. From ancestral times, the idea of enlightenment has been symbolized by the life cycle of the sacred lotus plant, whose life starts humbly in the mud yet eventually produces exquisite, untainted flowers, showing the path of spiritual enfoldment. Thus the sacred lotus has a deep ritual meaning to Hindus and Buddhists alike, to whom the lotus flower symbolizes beauty, purity and divinity. Most deities of Asian religions are depicted as seated on a lotus flower. In Buddhist temples, lotus is burned in powdered form as ceremonial incense and the flowers are given as a sacred offering in many Eastern temples. A thread made from the leaf stalks is used for making oil-wicks for lamps in temples. Cloth woven from this yarn is believed to cure many ailments and is used to make Buddhist robes; lotus seeds are also used to make malas (strings of prayer beads). The sacred lotus is the national flower of India and Vietnam.
ACTIONS: Antibacterial, antimicrobial, antidepressant, anti-oxidant, refrigerant, rejuvenating, sedative, tonic (heart, immune system, nervous system), vasodilator.
EXTRACTION: An absolute by solvent extraction from fresh flowers. The CO2 extraction process achieves a cleaner end product that is true to the oil and is thicker than other extraction methods. This product is often adulterated or blended with other oils (see other uses).
CHARACTERISTICS: A viscous liquid with an intense rich, sweet-floral scent and a spicy-leathery undertone. It blends well with tuberose, jasmine, neroli, rose, gardenia and spice oils.
PRINCIPAL CONSTITUENTS: The absolute (and oil) was found to be comprised mainly of palmitic acid methyl ester (22.66 per cent), linoleic acid methyl ester (11.16 per cent), palmitoleic acid methyl ester (7.55 per cent) and linolenic acid methyl ester (5.16 per cent) with myristic acid and oleic acid.
SAFETY DATA: Generally considered a safe oil.
AROMATHERAPY/HOME: USE
