Medour et al. (2002) carried out an ethnobotanical survey of medicinal plant use in two rural municipalities in the province of Bouira, Northern Algeria. This is a biodiverse, mountainous, Berber-speaking region with a rich ethnobotanical knowledge system.
Data were compiled from 69 informants among the local population and on 136 plant species. Data were gathered and data analyses were provided on:
- Socio-demographic profile of the informants.
- Diversity of medicinal plants.
- Toxic plants.
- Plant parts used, mode of preparation and administration.
- Diseases groups, treated diseases and number of use reports.
- Relative frequency of citation of the plant species recorded.
- Frequency of use of the plant species recorded.
- The percentage of informants claiming the use of a certain plant species for the same major purpose.
- Consensus among informants for plant use for the different disease categories recorded.
Among the many interesting data provided in this quantitative survey, the most interesting for me were those on the most used medicinal plants for various types of symptoms or conditions. These are summarised in the table below, taken from the cited paper .
Of particular interest to me personally are the reported uses of several plants commonly found in my own bio-region of Ibiza, Balearic islands, Spain, namely:
Allium sativum: Hypertension.
Cynara cardunculus: Diabetes.
Ditricchia viscosa: Arthritis.
Juniperus oxycedrus: Furuncles.
Lavandula stoechas: Colon pain.
Mentha spicata: Flu.
Olea europaea: Arthritis.
Papaver rhoeas: Colon pain.
Pinus halapensis: Flu.
Urtica dioica: Hair loss.
