Step 2: Decide which way to fold your binding. Besides direction, you also need to think about how you're going to fold and press your binding. You can simply fold binding in half along the entire length, which is called double fold because it's double the fabric when sewn.
What Is Histamine? Histamine is an important part of your bodyâs immune response, but high levels of the chemical compound can cause health problems. Histamine is a chemical produced in cells throughout the body as part of the bodyâs inflammatory response to allergy, infection, or injury. When damaged or exposed to allergens, cells in the skin, nose, throat and lungs release histamine, resulting in pain, itchiness, redness, runny nose, and wheezing.
By Sally Robertson, BSc. Histamine is a biologically active substance that plays a key role in the bodyâs inflammatory reaction to injury caused by infection, physical damage or allergy. Histamine is widely distributed throughout the animal kingdom and is also present in insect venom, many plants and bacteria.he increased permeability of blood vessels allows immune cells and substances to migrate from the bloodstream, through the vessels and into the site where injury or infection has occurred. Leukocytes and blood plasma proteins can then begin the process of fighting infection and healing the tissue.
