The recurrent aphthous stomatitis (RAS) is a common disease of the oral mucosa, manifested by recurrent mucosal ulcers 1,2 . The etiology of RAS is still unclear, but the predisposing factors include trauma, microbial infection, indigestion, blood disorders, emotional disorders (e.g., stress and worry), immunological disorders, nutritional deficiency, genetic disorders, allergy, and hormones (e.g., menstruation cycle) 3,4 . The etiopathogenetic basis is an inflammation due to Streptococcus sanguinis; this organism is one of the normal flora in the oral cavity but can cause an antigenic reaction and recurrent ulcers on the oral mucosa. Immunological changes are an underlying etiology of the oral mucosa inflammation, and the tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) cytokines play a key role in ulcer progression of oral cavity 4,5 .The primary strategy for RAS treatment is to control the inflammation, to suppress the inflammationassociated cells' activity, reducing the pain of the lesion, and accelerating the healing process 3 . The most commonly used anti-inflammatory agents to treat oral cavity inflammations are topical corticosteroids 6,7 . However, the Indonesian government is currently promoting the use of herbal medicines as alternative treatments
