This therapy is primarily used to decongest the abdomen and open the airways.
The onions are cut into stripes at the top, placed in a bowl of hot water, and boiled until the onion “opens” and the active substances are released.
These substances are mainly flavonoids, phenolic compounds, and sulfur compounds responsible for its aroma. Anthocyanins, a type of flavonoid, are responsible for the purple onion’s color. Significant amounts of myricetin and quercetin are also present.
One of the benefits of onion is that the quercetin it contains is easily absorbed by our bodies, up to four times faster than quercetin found in apple or tea.
An important advantage of onions is that the cooking processes do not reduce its flavonoid content, allowing the water in which it is boiled to contain amounts that are useful in our therapy.
Iron, calcium, potassium, and sodium are also present in onion, in addition to vitamin C.
Cotton compresses are immersed in boiling onion water. Water contains the active substances, as previously stated. To maximize their effect, they must be placed on your abdomen at the highest temperature you can tolerate. To keep the compress warm as long as possible, it is covered with a towel.
The therapist will leave you lying down for three to five minutes before returning with a new compress to replace the old one. They will cover it with a towel again and repeat the process once again for a total of three times.
You can take this therapy in the comfort of your room or lying on a chaise lounge on the beach.
