The human body is a maze within its own flesh.  True, there are some similarities to earth in that the body is largely made of water or fluid.  That being said the body has its own roads, routes, houses, abundance of green land, business functions and sites of interest. The landscape of the earth with regards to the location and direction of places tends to change. Structures within get worn down or there becomes a need to build more housing or places of employment in order keep the land functioning and in existence. The body works the same way in that when it ages it creates an old town of itself and some areas get created anew and other changes occur either naturally or cosmetically that enhances its look.

When roads need to be created or expanded new highways are built. This changes an atlas,map or gps because the directions are not the same as they once were as new places are added and old areas may no longer exist. The world and land within consists of many places known to people as "back roads". These roads are usually difficult to travel on and are not often used for frequent or otherwise known as commercial travel.  The body also consists of areas that may be viewed upon as "back roads". Because, to arrive at a condition in a particular area of the body, one may not have expected the travel or cause that originated from such a place to create a condition in another. You put more wear and tear on a car and its tires by driving on bumpy unpaved roads than you do on smooth ones.

Parathyroid glands are small glands that are located in the neck right behind the thyroid.  The parathyroid glands control the amount of calcium in our bodies. Calcium is an electrolyte that provides the electrical impulses that travel along nerves in our body. It is with the calcium that conducts electricity in the body. It also provides electrical energy for our muscular system.  Calcium gets stored in the bones. When a person has too much calcium in their body it enters the bloodstream and attaches itself to the arteries.  When too much calcium is produced it makes an excess of PTH or parathyroid hormone. This is called hyperparathyroidism.  As the excess hormone or PTH in abbreviation, goes from the bones to the bloodstream it ultimately removes calcium from the bones causing osteoporosis.  Since the calcium gets lodged in the arteries as it stays in the bloodstream your arteries become clogged.  Not only could your blood tests show an electrolyte imbalance ie. potassium or magnesium but your EKG or electrocardiogram may result in an abnormal result due the P waves in the atrium indicating abnormal electrical activity.

Are the parathyroid glands the "back roads" travel to the heart?

There are four of them. Just as there exists a North, South, East and West. Witches are also assigned to each one of these directions.  Last time I clicked my heels, I was about five. I never left Kansas, so what happened in Kansas definitely stayed there.

A heart abnormailty known as mitral regurgitation occurs when the valves of the heart do not close properly and because of that, blood is allowed to flow backwards. This is often referred to as a "leaky valve".  As the blood moves in flow of an area to travel to, if an opening exists the blood will then occupy the closest valve to enter or re-enter.  Mitral regurgitation can be a mild situation or it can be the result of CAD or coronary artery disease or brought on by myocardial ischemia, infarction or a heart attack.  This all results from the "back roads" of the parathyroid glands that cause damage from producing too much calcium that gets released into the bloodstream and clings to the arteries because it cannot be dissolved in a way that it would leave the arteries unaffected once it passes through them.

It is the back road or the parathyroid glands that need to be constructed into a major road for human commercial destination in order to arrive at correcting the arteries and valves of the heart.  

IDEA:

If an external patch, strip or rub on compound composed of EDTA(ethylenediaminetetraaceticacid) or any compound that includes Caysine(for proper calcium balance), Lysine(it helps lower cholesterol and absorbs calcium) along with antioxidants; were used on the parathyroid glands this could reduce heart disease by preventing them from being clogged; which prevents the artery valves from closing properly.  How could this be, right here in Kansas?  Such a chemical compound of EDTA, Caysine, Lysine can be used as a calcium absorber so that instead of leaving the bones dry and creating osteoporosis and then connecting to the arteries giving rise to CAD, the excess calcium will then be able to be passed through our bodies normally by urine.  Once calcium buildup is regulated and the excess converted and released by urine; the arteries will remain healthy because they will no longer be at risk for being clogged resulting from calcium buildup.  Like a door that swells or becomes too hard and difficult to close, unless a weatherizer is used to help maintain it from seasonal elements; heart arteries and valves are the same. When the arteries and valves are clear from plaque they are able to open and close properly. Symptoms of Mitral regurgitation or "leaky valve" include: heart murmur, coughing at night or coughing while laying down, edema in swollen feet or ankles, palpitations, fatigue and frequent urination.

Strange, but in all my travels- I've never met the good witch or the one that heals!
