Texte intégral

1The city of Valencia is the capital of the Valencian Region and also of the L'Horta district. It is situated in the centre of an alluvial, irrigation plain crossed by eight main irrigation channels: four on each side of the river Turia. The municipal area covers some 134.7 km2, stretching 30 km from north to south but barely 7km from east to west. Its official population in 1996 was 746,683 with 764,924 actually living there.

2No information was available about the use of medicinal plants by the population before hand. Publications on this subject range from first rate botanical research to those aimed at a wider audience. None of them takes into account data obtained from field work and they provide very little information about present-day uses in folk medicine.

Research objectives

3The methodological approach and objectives of this research are the same as those used by our group in La Ribera Alta region (Valencia) and the towns in the proximity of the La Albufera lake (Valencia). Our intention is to determine which plants are used in folk medicine in the city of Valencia, the names they are known by, the parts used and how they are prepared and administered, and finally, their therapeutical purposes. In this particular case, we also sought to determine differences that may exist in comparison with the results obtained in rural areas.

Material and methods

4Three hundred semi-structured interviews conducted over a ten year period (1986 - 1996) were selected from the ethnographic material housed in the Instituto de Historia de la Ciencia y Documentación (CSIC-UV), eliminating those involving herbalists and health science experts. After checking the botanical nomenclatures, the information obtained was classified by families, genera and species. The original, colloquial names and descriptions of their uses have been retained since this is precisely one of the aspects of most importance to us in this research. We have used such terms to compile a thesaurus enabling us to then draw up an overview of the folk-illnesses encountered in Valencian folk medicine.

5At no time has our sample purported to be representative of the entire population. Of the 300 interviews, 127 interviewees were men and 173 women. Table 1 shows their distribution by age and Table 2 by level of education.

Results

The families

6Table 3 shows the distribution by botanical families of all the species of plants used in folk medicine in the city of Valencia. As we can see, unlike the outcome of research in La Ribera Alta and in the municipalities of the Parque Natural de l'Albufera, the compositae family was the largest group (18), followed in descending order by the labiatae (14) and rosaceae families (8), with the gramíneae (7) and leguminosae (7) families in fourth and fifth position.

The species

7A comparison of these results with those of our earlier research (table 4) reveals that a total of 146 species belonging to 64 families were reported in the city of Valencia as opposed to 126 in La Ribera (54 families) and 110 in the municipalities of the Parque Natural de l'Albufera (49 families). Four levels of use were defined for the most frequently used. The first level includes the 13 plants used most frequently in the sample (8.90% of the total botanical species), which are:

8Camellia sinensis (L.) Kuntze (Theaceae) or tea (té)

21The second level includes 8 plants (5.47% of the total botanical species):

22Achillea millefolium L. (Compositae) or yarrow (mil en rama)

23Althaea officinalis L. (Malvaceae) or marshmarrow (malvavisco)

24Cynara scolymus L. (Compositae) or artichoke (alcachofa)

28Jasonia gluticosa (L.) DC (Compositae) or mountain tea (té de monte)

29Ruta angustifolia Pers. (Rutaceae) or rue (ruda)

30Twenty-four plants lie in the third level (16.43% of all the botanical species):

31Allium cepa L. (Liliaceae) or garlic (ajo)

32Allium sativum L. (Liliaceae) or onion (cebolla)

33Arctostaphylos uva-ursi (L.) Sprengel or bearberry (gayuba)

34Artemisa vulgaris L. (Compositae) or mugwort (artemisa)

35Ecballium elaterium L. (Cucurbitaceae) or cucumber (pepino)

36Frangula alnus Miller (Rhamnaceae) or alder buckthorn (frángula)

37Gentiana lutea L. (Gentianaceae) or gentian (genciana)

38Herniaria glabra L. (Caryophilaceae) or arenaria (rupturewort)

39Hordeum vulgare L. (Gramineae) or barley (cebada)

40Hypericum perforatum L. (Guttiferae) or St-John's-wort (hipericón)

41Juniperus communis L. (Cupressaceae) or common juniper (enebro)

42Lycopersicum esculentum Miller (Solanaceae) or tomato (tomate)

43Origanum virens Hoffmanns & Link. (Labiatae) or marjoram (orégano)

44Oryza sativa L. (Gramineae) or rice (arroz)

45Raphanus sativus L. (Cruciferae) or radish (rábano)

46Petroselinum crispum (Miller) A.W. Hill or parsley (perejil)

47Sambucus nigra L. (Caprifoliaceae) or elder (sauco)

48Santolina chamaecyparissus L. (Compositae) or lavender cotton (manzanilla amarga)

52Theobroma cacao L. (Sterculiaceae) or cocoa (cacao)

53Triticum aestivum L. (Gramineae) or wheat (trigo)

54Thymus vulgaris L. (Labiatae) or thyme (tomillo)

55Finally the fourth level includes those plants that did not comply with the criterion established by Johns, T. et al., i.e. those mentioned in fewer than three interviews. This group includes a total of 101 species, i.e. 69.17% of the total.

56The first striking fact is that, in the city of Valencia, unlike in La Ribera Alta and the Parque Natural de l'Albufera municipalities, most of the first level plants used are not autochthonous and many are not even grown in the area. This seems logical bearing in mind that city dwellers have less access to them than inhabitants of rural areas. There are however a greater number of specialist shops where they can be bought.

Use in folk medicine

57We have retained colloquial terms as we did in our research on the plants used in folk medicine in the Parque Natural de L'Albufera municipalities and La Ribera Alta area. According to linguistics, such terms objectivize and consolidate the knowledge that people have of health and disease, at least in part. We also know that the constitution of the meaning of language has a historical element and consequently, the meaning of the commonplace words in a language evolve constantly. It would be very interesting in this respect to know how a plant that has been used traditionally to remedy certain complaints, is now attributed properties known by names taken from modern, scientific medicine such as "reduce cholesterol", "scurvy", "sinusitis", etc.

58This process is closely linked to the needs, interests, scope and culture of each community. Language is also closely linked to people's world-view therefore the expressions we have recorded can help bring us at least a little closer to the general public's concept of disease. We are however aware that a great deal of research is still necessary, particularly into the structure and function of the different parts of the body and also disease and its origins. Although we cannot rid ourselves of the knowledge and taxonomy inherent in present-day modern, scientific medicine, we have created a simple thesaurus of the expressions recorded with reference to the use of medicinal plants. Thesauri are at present the most effective tool for controlling vocabulary in a data collection system.

59Our thesaurus consists of an alphabetical list of the generic and- specific relationships between terms (See the example in Table n° 6). The semantic trees are indented and offer the complete set of each hierarchy stemming from a main generic term. The numbers appearing next to each expression are those of the botanical species in the plant inventory. The expressions in inverted comas - of which there are very few - were added by us. A total of 247 different uses were recorded. Table n° 7 shows the number of botanical species used in folk medicine to remedy the pathological complaints encompassed by the main generic terms. The group of complaints for which the largest number of botanical species is used in Valencia, comes under the heading of "digestive problems". This is totally in keeping with previous research. In the present study however, "blood problems" and "circulation" are in second place, followed by "respiratory problems", "external complaints", and everything requiring "tonics, stimulants and vitamin supplements", and in sixth place, the processes that affect the kidneys and urinary tracts. These results differ considerably from those obtained in the La Ribera Alta and L'Albufera, and are very interesting although we cannot be sure what they are due to. One explanation could be that many of the people in the sample have a high level of education and that in this instance the zone under study is a large city. The pattern is more like the results obtained in other places in Europe and the USA although the type of study was different.

60A close look at the inventory and the complementary information it contains about each plant reveals that in most cases, their use in folk medicine can be scientifically justified. In others however, such as plants we could call multipurpose, not all their uses can be scientifically explained. This type could include those based on magic whose provenance was lost in the remote past eg juniper galbuli carried in the pocket to cure haemorrhoids, picking Centaura calcitrapa on St John's night, using rue to stave off evil eye, or rosemary to find "true love". One might think that this type of magic remedies were transmitted orally from one generation to the next but such recipes appear in some extant fragments of documents from Classical times, in medieval manuscripts and also in early printed books. The advent of the printing press made it possible to publish books for the general public about all sorts of remedies to combat disease. One classic example is the Libro de medicina llamado Tesoro de pobres en que se hallarán remedios muy aprobados para la sanidad de diversas enfermedades (1519) attributed to Petrus Hispanus, which was reprinted many times in different versions. Literature is also full of instances that mention magical remedies to combat illnesses and misfortunes, the best known of which include Lazarillo de Tormes, La Celestina and the Retrato de la Lozana andaluza.

61Some uses originated in classical, scientific medicine and remained unchanged or were distorted by different influences as time went by. Others obviously originated in modern, scientific medicine - both present-day and that of the 19th century - sometimes conserving the scientific meaning and sometimes redefining it within the framework of folk medicine. It would be particularly interesting in this respect to know which plants used traditionally have found new applications such as "lowering the level of cholesterol in the blood". Finally, people use plants that are totally foreign to their own territory, as this study clearly demonstrates. Some, such as tea, coffee, eucalyptus, boldo etc, were integrated into local heritage in the past, whilst others such as guarana and ginseng, from completely different places and medical systems, have been acquired recently. The media - press, radio, TV, etc - play an important role in diffusing them, as do shops selling plants and new-style food supplements. John K. Crellin provides a good description of an example of this in Newfoundland (Canada). Chart n° 1 is an attempt to portray the complex relationships and influences involved in the use of plants in folk medicine.

62Notes on the origin of actual popular uses of most frequent plants in the sample (level 1)

63Senna (sen) is one of the plants available in shops and is often an ingredient of the mixtures sold as slimming aids, laxatives etc. It originated in Arabia and spread subsequently throughout India. It does not feature in Materia Medica by Dioscorides but is mentioned in Andrés Laguna's commentaries on chapter 79, Book III, about Delphinio which was said to be grown usually in Italy. The species usually employed are Cassia angustifolia or Arabian senna and C. acutifolia or Alexandrian senna. The senna found in Spain is C. obovata, apparently introduced in the 18th century, much later than in Italy. It is used for the same reasons in folk medicine and by the medical profession. It must however be remembered that extended use can cause colon problems. This plant is nevertheless often included in "dietary products with fibre" under the generic name of "pulse flour" giving rise to many cases of rectocolitis.

64The orange tree (naranjo) is very well-known and held in high esteem in Valencia although it originated in the east. The properties of its flowers (orange blossom) are common knowledge, and in recent decades, due to the considerable impact of modern medicine, great importance has been given to the vitamin C content of its fruit. It is eaten habitually in Valencia to prevent common colds. Besides oranges, grapefruit and lemon are also used frequently.

65Despite having been introduced to Valencia as late as the 1860's, the eucalyptus (eucalipto) has taken root well in this region and is to be found in the streets and gardens of the city and the surrounding areas. The household use of this plant undoubtedly arose from the use that scientists made of it in the second half of the 19th and early decades of the 20th century. Its vapours are used in Valencia to remedy bronchitis, asthma, coughs and sinusitis, to soothe sore throats and even combat acne.

66Lemon verbena (marialuísa or hierbaluísa) is a plant that originated in South America and was introduced into southern Europe by the Spanish. It is also grown in northern Africa and Morocco is now one of its main producers. Its name is said to have come from that of the wife of Charles IV of Spain. It is grown in kitchen gardens, gardens and plant pots. Its applications in folk medicine are basically the same as those described by scientists. In Valencia, it is mainly used in folk medicine as a painkiller (stomach aches, period pains, toothache etc).

67As regards mallow (malva), we can say that it was already known in Classical times. It figures in Dioscorides' Materia medica with properties similar to those in present-day folk medicine as a pectoral, laxative, to combat rheumatic pain, to cleanse wounds, for eye infections etc. We found that it could be used to soothe bites, a fact reminiscent of the use recommended by Dioscorides as a remedy for bees and wasp stings. Its very high mucilage content means mallow can calm coughs and is an effective emollient. The Iberian Peninsula is home to another one and a half dozen mallows with constituents similar to those of the silvestris variety.

68Camomile (manzanilla) is a widely used plant that originated in Europe and the north of Africa. It was undoubtedly known in Classical times, but there is apparently considerable confusion in the texts describing other species similar in appearance. Chapter 16 of Dioscorides' Materia Medica on camomiles, for example, distinguishes three different species, whilst chapter 149 on Parthenio, is said by Laguna to be none other than the matricaria. As the inventory shows, this plant has many uses in folk medicine, most of which have been confirmed by scientific research. It is taken internally for digestion problems and externally for eye complaints.

69Mint (menta) is also a plant that originated in Europe. It is very widespread and often naturalised in many locations. It is a sterile hybrid from England that is consumed In vast quantities in both Europe and the United States. A certain Eales was the first to observe it in Hertfordshire. He notified Ray, who included it in the second edition of Synopsis Stirpium Britannicarum (1696), under the name of "Mentha spicis brevioribus et habitioribus... ", and in his Historia plantarum (1704), as Mentha palustris...Peper-Mint". It entered the London Pharmacopoeia of 1721 as Mentha piperitis sapore. In the region of Valencia, other varieties are possibly consumed under this name since it has become a generic term used to describe several species. The applications in folk medicine that we have recorded are very similar to its scientific uses. Its main application in Valencia is to remedy digestive problems (particularly to prevent vomiting), and also dizziness, headaches and as a depurative etc.

70Another commonplace plant not grown in Spain is boldo, which originated in the dry mountains of Chile and is grown sporadically in Italy and the north of Africa. It is therefore a plant which was introduced late. According to Dujardin-Beaumetz in a paper we located in the Bibliothèque Nationale, Paris, it was described by Molina in 1782 under the name of Peumus boldus. He goes on to say that in 1782, Ruiz and Pavόn described the same plant, which they called Ruizia fragans. In 1807 Person baptised it as Peumus fragans and in 1809, on the basis of the preceding research, A.L. de Jussieu called it Boldea fragans. M. de Candolle took up Peumus again as the name for the genus. In 1869, in his Histoire des plantes, H. Baillon provided a comprehensive study of boldo, which he referred to as Peumus boldus - the name by which it is known today. Dujardin also said that boldo was first introduced into French trade in 1868 or 1869 by the Chilean company Fabian. Since there were several varieties, the different samples were analysed in order to isolate and compare their active principles. It is used in folk medicine in Valencia to protect the liver and as a choleretic-cholagogue, properties of its boldine and alkaloid content in conjunction with flavonoids and essential oil.

71Anise (anís or matalahúva) is a plant from eastern Mediterranean countries. It was known to and used by the Egyptians. It is mentioned in the work of Pliny, Theophrastus and in Dioscorides1 Materia Medica. Spain and Greece are the main producers of anise essential oil. According to Flükiger, Alicante was one of the places where it was made and sold. We found it was used in folk medicine in Valencia for the same reasons as ever: for its carminitive properties.

72Rosemary (romero) is a plant that originated in the Mediterranean countries. Long ago, Pliny attributed it many powers. Andrés Laguna, in his commentary on chapters 81, 82 and 83 about Libanotis in Materia Medica by Dioscorides, identified the third species as rosemary. The preparation of rosemary essence in an alcoholic solution is frequently attributed to Arnau de Vilanova or Ramón Llull. Its use has always been highly praised in treatises on household medicine. In Valencia, rosemary has many uses in folk medicine - many of which have been confirmed by scientific research.

73Sage (salvia) originated in southern Europe, particularly in the Mediterranean area. It features in Materia Medica by Dioscorides. The varieties used are Salvia officinalis, S. lavandulifolia and other similar species, whose essential oil is less toxic than that of the first, endemic to the Iberian Peninsula. Most of its household uses have been completely ratified by pharmacological research. It is used in Valencia to combat bronchitis and colds, period pain, cramps and also as a vasodilator, to improve the circulation, "regulate the sugar in the blood", etc. However, little is known about its toxicity. It has an oestrogenic effect and can cause contact dermatitis and be detrimental to the central nervous system.
