The plant is sometimes cultivated for its edible leaves in parts of Asia, especially Malaysia, Indonesia, the Philippines, Taiwan and Japan.

Edible Uses: Leaves – raw or cooked. Added to salads or soups. The leaves contain about 1.5% protein, 0.4% fat, 2.2% carbohydrate, 0.7% ash. Stem – cooked. It contains 0.6% protein, 0.1% fat, 2.1% carbohydrate, 0.5% ash. Leaves and tender stems with slight bitterness are used fresh as salad, boiled, steamed or stir-fried, or in soup.

Medicinal Uses:
Beta-carotene: high; riboflavin: medium; ascorbic acid: medium; calcium: medium; iron: high; protein: 2.2%. Leaves contain also six antioxidative phenolic compounds.

The entire plant, and especially the leaves, is employed as a depurative and demulcent The leaves are used in treating mastitis, galactophoritis, furunculosis and abscesses. They are also effective for gastralgia and dyspepsia. The usual dose is 8 to 20g per day in the form of a decoction, extract or syrup. A mixture with some other plants is used externally in the form of a poultice of pounded fresh leaves.

The plant is digestive and tonic. Although we have seen no specific reports for this species, most if not all members of the genus have a milky sap that contains the substance ‘lactucarium‘ and can probably be used as the report below details. The whole plant is rich in a milky sap that flows freely from any wounds. This hardens and dries when in contact with the air. The sap contains ‘lactucarium’, which is used in medicine for its anodyne, antispasmodic, digestive, diuretic, hypnotic, narcotic and sedative properties. Lactucarium has the effects of a feeble opium, but without its tendency to cause digestive upsets, nor is it addictive. It is taken internally in the treatment of insomnia, anxiety, neuroses, hyperactivity in children, dry coughs, whooping cough, rheumatic pain etc. Concentrations of lactucarium are low in young plants and most concentrated when the plant comes into flower. It is collected commercially by cutting the heads of the plants and scraping the juice into china vessels several times a day until the plant is exhausted. An infusion of the fresh or dried flowering plant can also be used. The plant should be used with caution, and never without the supervision of a skilled practitioner. Even normal doses can cause drowsiness whilst excess causes restlessness and overdoses can cause death through cardiac paralysis. Some physicians believe that any effects of this medicine are caused by the mind of the patient rather than by the medicine. The sap has also been applied externally in the treatment of warts.

Cultivation:
Prefers a light sandy loam. We do not know how hardy this plant will be in Britain, though it can be grown here as an annual. It takes about 60 days from seed sowing until the first leaves are harvested. This species is sometimes cultivated for its edible leaves in Asia. It originated in China but is now cultivated in many parts of S.E. Asia.

Propagation:
Seed – sow early spring in a warm greenhouse, only just covering the seed. Germination is usually rapid, prick out the seedlings when large enough to handle and plant them out after the last expected frosts. Division in spring. Make sure each piece of root has a leaf bud. Root cuttings in late winter.

Known Hazards : Although no specific mention of toxicity has been seen for this species, many plants in this genus contain a narcotic principle, this is at its most concentrated when the plant begins to flower. This principle has been almost bred out of the cultivated forms of lettuce but is produced when the plant starts to go to seed.

Fruit type (general): the fruit is dry and splits open when ripe
Fruit length: 3–4 mm..click & see
Cultivation:
Prefers a moist sandy woodland soil in a cool position with partial shade. This is a very ornamental but difficult plant to grow. It requires a mycorrhizal relationship in the soil and therefore needs to be grown initially in soil collected from around an established plant. It is also very difficult from seed as well as being intolerant of root disturbance which makes division difficult. The flowers have a soft almond scent.

Propagation:
Seed – the only information we have on this species is that it is difficult from seed and germinates infrequently. We would suggest sowing the seed as soon as it is ripe if this is possible. Sow it into soil collected from around an established plant, only just covering the seed, and put the pot in a shady part of a cold frame. Pot up any young seedlings as soon as they are large enough to handle, once again using soil from around an established plant. Plant out into their permanent positions when the plants are large enough. You should not need to use soil from around an established plant to do this since the soil in the pot will contain the necessary micorrhiza. Division with great care in the spring[1, 111]. Pot up the divisions using some soil from around an established plant, grow on in a lightly shaded part of a greenhouse or frame and do not plant out until the plants are growing away vigorously

Edible Uses: Edible Parts: Fruit; Leaves…..Fruits & Leaves are said to be eaten raw

Medicinal Uses: The plant is antispasmodic, astringent, diuretic and tonic.

CLICK & SEE THE PICTURES

It is in flower from Apr to May. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects
Cultivation:
Succeeds in a most humus-rich lime-free soils except those of a dry arid nature or those that are heavy or clayey[1]. Prefers a peaty or well-drained sandy loam. Succeeds in sun or shade, the warmer the climate the more shade a plant requires. A pH between 4.5 and 5.5 is ideal. Succeeds in a woodland though, because of its surface-rooting habit, it does not compete well with surface-rooting trees. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers[200]. Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact. Plants in this genus are notably susceptible to honey fungus.
Propagation:
Seed – best sown in a greenhouse as soon as it is ripe in the autumn and given artificial light. Alternatively sow the seed in a lightly shaded part of the warm greenhouse in late winter or in a cold greenhouse in April. Surface-sow the seed and do not allow the compost to become dry[200]. Pot up the seedlings when they are large enough to handle and grow on in a greenhouse for at least the first winter. Layering in late July. Takes 15 – 24 months[78]. Cuttings of half-ripe wood, August in a frame. Easy

Edible Uses:: A tea is made from the leaves and flower tips.

Medicinal Uses: Not yet known.

Known Hazards: Although no specific mention of toxicity has been seen for this species, it belongs to a genus where many members have poisonous leaves. The pollen of many if not all species of rhododendrons is also probably toxic, being said to cause intoxication when eaten in large quantities.

It grows in moist woods and flowers from July to September. The rhizome is brown-grey, about 4 inches long, knobby, and very hard. The whole plant has a strong, disagreeable odour and a pungent and spicy taste. The chief virtue of the plant is in the root, which should always be used fresh. The name is derived from its discoverer, Peter Collinson….CLICK & SEE THE PICTURES

It is in flower in August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.
Cultivation:
Prefers a sandy peat in a moist situation but it is easily grown in ordinary garden soils so long as they are not dry. Prefers dappled shade. The whole plant has a strong disagreeable odour and a pungent spicy taste. Another report says that the foliage is strongly aromatic, with a lemon scent.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame. The seed can also be sown in the spring, though it might be slower to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in a greenhouse or cold frame. Plant them out in spring or early summer of their second year. Division in spring.

Parts Used: Whole plant, fresh root.
Constituents: In the root there is resin, starch, mucilage and wax. In the leaves, resin, tannin, wax and volatile oil. The alkaloid discovered in the root appears to be a magnesium salt.

Medicinal Uses:
Alterative; Antispasmodic; Diaphoretic; Diuretic; Sedative; Tonic; Vasodilator; Vulnerary.

The whole plant, but especially the fresh root, is alterative, antispasmodic, diaphoretic, diuretic, sedative, tonic, vasodilator and vulnerary. A tea made from the roots is strongly diuretic, it is valuable in the treatment of all complaints of the urinary system and the rectum and is used in the treatment of piles, indigestion, diarrhoea, kidney complaints etc. It has proved of benefit in the treatment of irritable bowel syndrome, mucous colitis and varicose veins. The root is seldom used on its own but is contained in remedies with other herbs, especially Aphanes arvensis, Eupatorium purpureum and Hydrangea arborescens. The roots contain more than 13,000 parts per million of rosmarinic acid, the same anti-oxidant that is found in rosemary. The fresh leaves are strongly emetic. Some caution is advised, see notes above on toxicity. A poultice of the leaves or roots is applied to burns, bruises, sores, sprains etc
A decoction of the fresh root has been given in catarrh of the bladder, leucorrhcea, gravel and dropsy. It is largely used by American veterinary surgeons as a diuretic. It is valuable in all complaints of urinary organs and rectum, and is best combined with other drugs.

It can be used externally, especially the leaves, for poultices and fomentations, bruises, wounds, sores, cuts, etc., and also as a gargle, in the strength of 1 part of fluid extract to 3 of water.
