Echinacea is a plant used by Native Americans to treat mosquito bites. It is known as the “Indian Herb” and has been used as a natural medicine since ancient times. Echinacea extract has a positive immunomodulatory effect, but the ingredients contained in echinacea extract may have antagonistic effects with conventional medications for autoimmune diseases such as lupus erythematosus, and should not be directly used for the treatment of related diseases. Therefore, the higher the immunity, the better. It is generally recommended to take echinacea extract intermittently for a short period of time to improve immunity, but not for continuous long-term use.

紫锥花是北美洲原住民用来治疗蚊虫叮咬的植物，有”印第安的药草”之称，自古就被作为天然药品使用。紫锥花提取物有正向的免疫调节效果，但是紫锥花提取物所含的成分可能和红斑狼疮等自身免疫性疾病的常规用药产生拮抗作用，不得直接用于相关疾病的治疗。因此，免疫力不是越高越好，一般建议短期间歇性的服用紫锥花提取物可以提升免疫力，但不是连续的长期服用。
