Traditional Knowledge of Medicinal Plants in Relation to Local Customs and Practices of the North Black Sea Coast Population

This comprehensive ethnobotanical study was conducted along the North Black Sea coast area to find of the extent to which indigenous knowledge of medicinal plants and their relation to Bulgarian traditions and customs is preserved. We aim to identify the tendencies of passing this knowledge to future generations.

The survey was conducted in 2015 in various urban and rural North Black Sea coast areas, using a face-to-face interviews technique. We used the Chi-square test to analyse the results. Pearson correlation coefficient was used for the assessment of the impact of demographics on respondents' answers.

More than half of the respondents (61.08%) are not familiar with rituals and traditional practices related to medicinal plants. Moderate influence on respondents' answers is rendered by age only. For the local population of the North Black Sea coast, Enyovden turns out to be the most popular holiday related to medicinal plants. Enyovden is the herbalists' feast and is cited by 20% of respondents. The same percentage of interviewees mention Geranium spp. and Ocimum basilicum L. as the most favoured herbs related to local traditions and customs.

Traditional knowledge of the relation between Bulgarian rituals and customs to medicinal plants and their magical powers is fading.
