Leaves - cooked[105]. Very bitter, they are an emergency food that is
only used when all else fails[177]. A gel in the leaves is sometimes used as
an ingredient of commercial jellies[183].

Aloe vera is a fairly well known herbal preparation with a long history
of use. It is widely used in modern herbal practice and is often available in
proprietary herbal preparations[K]. It has two distinct types of medicinal
use. The clear gel contained within the leaf makes an excellent treatment for
wounds, burns and other skin disorders, placing a protective coat over the
affected area, speeding up the rate of healing and reducing the risk of
infection[254, K]. This action is in part due to the presence of aloectin B,
which stimulates the immune system[254]. To obtain this gel, the leaves can
be cut in half along their length and the inner pulp rubbed over the affected
area of skin[K]. This has an immediate soothing effect on all sorts of burns
and other skin problems[K].
The second use comes from the yellow sap at the base of the leaf. The leaves
are cut transversally at their base and the liquid that exudes from this cut
is dried[4]. It is called bitter aloes and contains anthraquinones which are
a useful digestive stimulant and a strong laxative[254]. When plants are
grown in pots the anthraquinone content is greatly reduced[254].
The plant is emmenagogue, emollient, laxative, purgative, stimulant,
stomachic, tonic, vermifuge and vulnerary[4, 21, 46, 57, 61, 165, 176].
Extracts of the plant have antibacterial activity[218].
Apart from its external use on the skin, aloe vera (usually the bitter
aloes) is also taken internally in the treatment of chronic constipation,
poor appetite, digestive problems etc[238]. It should not be given to
pregnant women or people with haemorrhoids or irritable bowel syndrome[238,
243]. The plant is strongly purgative so great care should be taken over the
dosage[238].
The plant is used to test if there is blood in the faeces[61].
This plant has a folk history of treatment in cases of cancer[218]. We have a more details factsheet on the history and medicinal use of this plant. Email webmaster@pfaf.org for details.
Other Uses
Cosmetic
Pollution.
The leaf extracts are used in skin-care cosmetic products[238, 254].
Plants have been grown indoors in pots in order to help remove toxins from
the atmosphere. It is also unusual in that it continues to release oxygen and
absorb carbon dioxide in the dark, making it very suitable for growing in
bedrooms[259].
Cultivation details
Requires a well-drained soil and a very sunny position[1]. Plants are
tolerant of poor soils[200]. If trying to grow this plant outdoors then it
will need the sunniest and warmest area in the garden plus some protection
from winter cold (a glass frame perhaps)[K].
This species is not very cold-hardy outdoors in Britain, it is best grown in
a pot placed outdoors in the summer and put in a greenhouse for the
winter[1]. It grows very well in a sunny windowsill[K].
Propagation
Seed - sow spring in a warm greenhouse. The seed usually germinates in
1 - 6 months at 16° c. Prick out the seedlings into individual pots of very
well-drained soil when they are large enough to handle. Grow them on in a
sunny part of the greenhouse for at least their first two winters. If trying
them outdoors then plant them out in early summer to allow them to become
established before the winter, and give them some protection from the cold in
winter[K].
Division of offsets when available, usually in spring. The plants produce
offsets quite freely and they can be divided at any time of the year as long
as it is warm enough to encourage fresh root growth to allow re-establishment
of the plants[K]. Pot up and grow on in the greenhouse until established.

[46] Uphof. J. C. Th. Dictionary of Economic Plants. Weinheim 1959 An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[50] ? Flora Europaea Cambridge University Press 1964 An immense work in 6 volumes (including the index). The standard reference flora for europe, it is very terse though and with very little extra information. Not for the casual reader.

[61] Usher. G. A Dictionary of Plants Used by Man. Constable 1974 ISBN 0094579202 Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[105] Tanaka. T. Tanaka's Cyclopaedia of Edible Plants of the World. Keigaku Publishing 1976 The most comprehensive guide to edible plants I've come across. Only the briefest entry for each species, though, and some of the entries are more than a little dubious. Not for the casual reader.

[176] Yeung. Him-Che. Handbook of Chinese Herbs and Formulas. Institute of Chinese Medicine, Los Angeles 1985 A very good Chinese herbal.
[177] Kunkel. G. Plants for Human Consumption. Koeltz Scientific Books 1984 ISBN 3874292169 An excellent book for the dedicated. A comprehensive listing of latin names with a brief list of edible parts.
[183] Facciola. S. Cornucopia - A Source Book of Edible Plants. Kampong Publications 1990 ISBN 0-9628087-0-9 Excellent. Contains a very wide range of conventional and unconventional food plants (including tropical) and where they can be obtained (mainly N. American nurseries but also research institutes and a lot of other nurseries from around the world.
[200] Huxley. A. The New RHS Dictionary of Gardening. 1992. MacMillan Press 1992 ISBN 0-333-47494-5 Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.
