An experienced inyanga/Sangoma will generally seek the guidance of an ancestral spirit before embarking to find and collect muti and you can also go to herbalists to ask for a certain plant/herb you need. The healer, through dreams or during prayers, believes they are advised of auspicious times for collecting the plants. In some cases, symbols and dreams are also interpreted to determine which particular plants to collect for a specific patient and where these plants are located, not in all cases as most traditional healers have their herbs stored in their huts("eNdumbeni"). The healer supplements the perceived advice from an ancestral spirit with their own knowledge, training and experience.
