Let's please avoid "rules lawyering" the topic to death here.  The article is improved by the presence of these sources.  Respectfully, Primary sources are not specifically banned under WP:WPNOTRS.  Their use in a list format in this case adequately avoids the pitfalls cited in WP:WPNOTRS regarding the use of primary sources.  That page says specifically that secondary sources are preferred, but does not ban primary sources.  No claim regarding the information in these sources is provided by the Young Living article and the sources do not represent a large block of material.
