  • Dermatophagoides farinae
  • Dermatophagoides pteronyssinus

Acaricidal Principles of Cinnamomum Cassia

A recent scientific study identified the acaricidal (chemicals used for controlling mites and ticks) principles that are present in the cassia bark and cassia oil. They include the following:

  • (E)-cinnamaldehyde
  • Salicylaldehyde

  • Occupational asthma
  • Occupational allergic or contact dermatitis

Scientific studies have reported that workers of cassia cinnamomum processing industry also suffer from following systemic problems:

  • Irritation of skin
  • Smarting of eyes
  • Loss of hair
  • Loss of weight

Non-Immune Reactions of Cassia Cinnamomum

The non-immune reactions of cassia include the following:

Based on histopathologic changes, cinnamon-induced stomatitis (swelling and irritation of mucous lining) is found. The following are the different types of cinnamomum cassia-induced stomatitis:

  • Hyperkeratosis
  • Chronic lichenoid mucositis with plasmacytic infiltration
  • Marked chronic perivasculitis.
  • Erythema multiforme (characterized by chronic extensive surface ulcerations and lip swelling)
  • Oral leukoplakia
  • Gastric irritation
