Re-explain the following in simple English

Some Western-trained health professionals do not like working alongside
traditional African healers. However, this attitude is based on cultural arrogance
and a limited understanding of the healers’ methods and effectiveness (Louw &
Pretorius, 1995)

Some doctors from the West do not want to work with African healers. But this is mostly because they think their way of healing is better and they don't fully understand how the African healers work and how well their methods actually work.
