PLEURISY with e?usion is a condition requiring aspiration, and a litre or more of ?uid may be drawn o? by an aspirator or a large syringe and needle. Chronic abscesses and tuberculous joints may call for its use, the operation being done with a small syringe and hollow needle. PERICARDITIS with e?usion is another condition in which aspiration is sometimes performed. The spinal canal is aspirated by the operation of LUMBAR PUNCTURE. In children the ventricles of the brain are sometimes similarly relieved from excess of ?uid by piercing the fontanelle (soft spot) on the infant’s head. (See HYDROCEPHALUS.)... aspiration
Structure
CORIUM The foundation layer. It overlies the subcutaneous fat and varies in thickness from 0·5–3.0 mm. Many nerves run through the corium: these have key roles in the sensations of touch, pain and temperature (see NEURON(E)). Blood vessels nourish the skin and are primarily responsible for regulating the body temperature. Hairs are bedded in the corium, piercing the epidermis (see below) to cover the skin in varying amounts in di?erent parts of the body. The sweat glands are also in the corium and their ducts lead to the surface. The ?brous tissue of the corium comprises interlocking white ?brous elastic bundles. The corium contains many folds, especially over joints and on the palms of hands and soles of feet with the epidermis following the contours. These are permanent throughout life and provide unique ?ngerprinting identi?cation. HAIR Each one has a root and shaft, and its varying tone originates from pigment scattered throughout it. Bundles of smooth muscle (arrectores pilorum) are attached to the root and on contraction cause the hair to stand vertical. GLANDS These occur in great numbers in the skin. SEBACEOUS GLANDS secrete a fatty substance and sweat glands a clear watery ?uid (see PERSPIRATION). The former are made up of a bunch of small sacs producing fatty material that reaches the surface via the hair follicle. Around three million sweat or sudoriparous glands occur all over the body surface; sited below the sebaceous glands they are unconnected to the hairs. EPIDERMIS This forms the outer layer of skin and is the cellular layer covering the body surface: it has no blood vessels and its thickness varies from 1 mm on the palms and soles to 0·1 mm on the face. Its outer, impervious, horny layer comprises several thicknesses of ?at cells (pierced only by hairs and sweat-gland openings) that are constantly rubbed o? as small white scales; they are replaced by growing cells from below. The next, clear layer forms a type of membrane below which the granular stratum cells are changing from their origins as keratinocytes in the germinative zone, where ?ne sensory nerves also terminate. The basal layer of the germinative zone contains melanocytes which produce the pigment MELANIN, the cause of skin tanning.
Nail A modi?cation of skin, being analagous to the horny layer, but its cells are harder and more adherent. Under the horny nail is the nail bed, comprising the well-vascularised corium (see above) and the germinative zone. Growth occurs at the nail root at a rate of around 0·5 mm a week – a rate that increases in later years of life.
Skin functions By its ability to control sweating and open or close dermal blood vessels, the skin plays a crucial role in maintaining a constant body temperature. Its toughness protects the body from mechanical injury. The epidermis is a two-way barrier: it prevents the entry of noxious chemicals and microbes, and prevents the loss of body contents, especially water, electrolytes and proteins. It restricts electrical conductivity and to a limited extent protects against ultraviolet radiation.
The Langerhans’ cells in the epidermis are the outposts of the immune system (see IMMUNITY), just as the sensory nerves in the skin are the outposts of the nervous system. Skin has a social function in its ability to signal emotions such as fear or anger. Lastly it has a role in the synthesis of vitamin D.... skin
Species causing disorders include the scabies mite, which burrows in human skin causing intense itching; the housedust mite, which can cause asthma when inhaled in dust; and chiggers (American harvest mites), which are found in thick grass and cause an itchy rash when they bite. Mites in grain or fruit may cause skin irritation, sometimes known as grocers’ or bakers’ itch.Certain mites transmit diseases, particularly scrub typhus and rickettsial pox.... mites and disease
Avoid overstocking; some herbs lose their potency on the shelf in time, especially if exposed. Do not keep on a high shelf out of the way. Experts suggest a large box with a lid to protect its contents, kept in a cool dry place away from foods and other household items. Store mixtures containing Camphor separately elsewhere. Camphor is well-known as a strong antidote to medicinal substances. Keep all home-made ointments in a refrigerator. However harmless, keep all remedies out of reach of children. Be sure that all tablet containers have child-resistant tops.
Keep a separate box, with duplicates, permanently in the car. Check periodically. Replace all tablets when crumbled, medicines with changed colour or consistency. Always carry a large plastic bottle of water in the car for cleansing dirty wounds and to form a vehicle to Witch Hazel and other remedies. Label all containers clearly.

Stings of nettles or other plants are usually rendered painless by a dock leaf. Oils of Tea Tree, Jojoba and Evening Primrose are also excellent for first aid to allay infection.

FAMILY: Lamiaceae (Labiatae)
SYNONYMS: L. spica, aspic, broad-leaved lavender, lesser lavender, spike.
GENERAL DESCRIPTION: An aromatic evergreen sub-shrub up to 1 metre high with lance-shaped leaves, broader and rougher than true lavender. The flower is more compressed and of a dull grey-blue colour.
DISTRIBUTION: Native to the mountainous regions of France and Spain; also found in North Africa, Italy, Yugoslavia and the eastern Mediterranean countries. It is cultivated internationally; the oil is mainly produced in France and Spain.
OTHER SPECIES: There are many different chemotypes of lavender in general, and this also applies to spike lavender. The French spike oil is reputed to be a more delicate, aromatic scent than the Spanish variety. For other varieties, see entries on lavandin, true lavender and the Botanical Classification section.
HERBAL/FOLK TRADITION: Culpeper recommends spike lavender for a variety of ailments including ‘pains of the head and brain which proceed from cold, apoplexy, falling sickness, the dropsy, or sluggish malady, cramps, convulsions, palsies, and often faintings’. He also warns that ‘the oil of spike is of a fierce and piercing quality, and ought to be carefully used, a very few drops being sufficient for inward or outward maladies’.. The preparation ‘oleum spicae’ was made by mixing ¼ spike oil with ¾ turpentine, and used for paralysed limbs, old sprains and stiff joints (it was also said to encourage hair growth).
Spike lavender is current in the British Herbal Pharmacopoeia, indicated for flatulent dyspepsia, colic, depressive headaches, and the oil (topically) for rheumatic pain.
ACTIONS: See true lavender.
EXTRACTION: Essential oil by water or steam distillation from the flowering tops.
CHARACTERISTICS: A water-white or pale yellow liquid with a penetrating, fresh herbaceous, camphoraceous odour. It blends well with rosemary, sage, lavandin, eucalyptus, rosewood, lavender, petitgrain, pine, cedarwood, oakmoss, patchouli and spice oils, particularly clove.
PRINCIPAL CONSTITUENTS: Mainly cineol and camphor (40–60 per cent), with linalol and linalyl acetate, among others.
SAFETY DATA: Non-toxic, non-irritant (except in concentration), non-sensitizing.
AROMATHERAPY/HOME: USE See true lavender.
OTHER USES: It is used in some pharmaceutical preparations and especially in veterinary practice as a prophylactic, in incipient paralysis, for rheumatism and arthritis and to get rid of lice. It is extensively employed as a fragrance component especially in soaps and industrial perfumes such as deodorants, disinfectants and cleaning agents, as well as insecticides and room sprays, etc. It is also used in the food industry and in the production of fine varnishes and lacquers.... lavender, spike
