The spice is any part of a particular plant that is utilized for flavoring or seasoning food. The spices might be acquired from the leaves, bark, roots, seeds, buds, fruit or other part of the plant. Unlike with spices, an herb is typically acquired from the leafy part of the plant and utilized to season or flavor foods. Just like with other foods, spice allergy is possible.
Even though spice allergy is uncommon, it is considered under-diagnosed. Several species have biological functions that enhance their ability to result in sensitization. An example is capsaicin which enhances intestinal absorption, possibly resulting to increased rates of sensitization.
Exposure to spices can occur in various ways, typically as a result of eating foods that contain spices. Nevertheless, exposure can also occur via contact with the skin such as handling foods and from cosmetics that might contain spices. Exposure can also occur through inhalation of airborne spices from occupational exposure.
