7. Recurrent upper respiratory tract in Children
In the research of immunostimulant herbal compound, including Echinacea angustifolia, Arabinogalactan, Acerola (Vitamin C), Beta- Glucan e Zinc (Imoviral® Junior) and its effect on recurrent upper respiratory tract infections found that the herbal compound of echinacea, beta-glucan, vitamin c, arabinoglactan and zinc (Imoviral® Junior) can improve the quality of life in pediatric patients affected by recurrent pharyngotonsillitis and otitis media without contralateral effects, according to "Efficacy of complex herbal compound of Echinacea angustifolia (Imoviral® Junior) in recurrent upper respiratory tract infections during pediatric age: preliminary results" by Minetti AM, Forti S, Tassone G, Torretta S, Pignataro L.(7)

Both herbal remedy users' and non-users' mental component summary scores on the SF-36 increased similarly from the first survey to the second survey (P=0.16), but herbal remedy users' physical component summary scores decreased more than those of non-users (-5.7 vs. -3.2, P=0.02), according to "The roles of herbal remedies in survival and quality of life among long-term breast cancer survivors--results of a prospective study" by Ma H, Carpenter CL, Sullivan-Halley J, Bernstein L.(8)

9. Embryonic palatal mesenchymal cells
In the demonstration of phenytoin and Echinacea purpurea extractand their effects in Cleft palate of most common birth defects found that mixture of phenytoin and E. purpurea extract increased the proliferation and decreased the apoptosis of MEPM cells as compared with treatment with phenytoin alone. The teratogenic effect of phenytoin on cleft palate is associated with the proliferation and apoptosis of MEPM cells, and E. purpurea extract may have a protective effect, according to "Effects of phenytoin and Echinacea purpurea extract on proliferation and apoptosis of mouse embryonic palatal mesenchymal cells" by
Hu X, Chen Z, Mao X, Tang S.(9)

10. Chronic-obstructive pulmonary disease
In the determination of Echinacea purpurea along with zinc, selenium and vitamin C and their efect in chronic-obstructive pulmonary disease found that The combination of EP, zinc, selenium and vitamin C may alleviate exacerbation symptoms caused by URTI in COPD. according to "Echinacea purpurea along with zinc, selenium and vitamin C to alleviate exacerbations of chronic obstructive pulmonary disease: results from a randomized controlled trial" by Isbaniah F, Wiyono WH, Yunus F, Setiawati A, Totzke U, Verbruggen MA.(10)
