The most common reason for the person having minimal results is that the person has got a digestive disorder such as stomach ulcers, hernia, constipation, reflux, heartburn, IBS, spastic colon, candida and windiness. If your digestive system is not happy then you build up excess acids, this in turn increases histamine production, which in turn increases mucous production or makes the bronchials go into a spasm (asthma forming). Should this be the case please consult your health professional so that the correct advice can be given so as to repair the digestive system, which in turn will allow the Sinus formula to work.

Why has my child got worse while using your remedy?

When taking this formula with a congested chest it brings out all the mucous and congestion on the lungs, your child normally swallows this excess mucous, which causes nausea and thus is brought up. This is a good sign and normally clears in two days.

Russian studies since the 1950’s have shown that Siberian ginseng appears to have a general tonic effect on the body, in particular on the adrenal glands, helping the body to withstand heat, cold, infection and other physical stresses. It has even been given to astronauts to counter the effects of weightlessness.

Most frequently asked questions about Gout & PhytoSun® Gout Atomiser

What is gout?

Gout is a form of arthritis that causes sudden, severe attacks of pain, tenderness, redness, warmth and swelling (inflammation) in some joints. It usually affects one joint at a time. The large toe is most often affected, but gout can also affect other joints in the leg and, less often, joints in the arm.


What causes gout?

Gout results from the abnormal deposit of sodium urate crystals in the joint cartilage that is later released into the joint fluid. Gout symptoms can be precipitated by stress, infection, joint injury, weight loss, surgery, certain kinds of drug treatments, over indulgence of alcohol or highly acidic foods, or even something as seemingly inconsequential as a long walk that one was not sufficiently physically fit to undertake.


What is uric acid?

Uric acid is not a fundamentally harmful substance, but a power anti oxidant, almost as effective as Vitamin C, that help protect cells from oxidative damage. It is only when levels become abnormally elevated that it becomes problematic. Approximately 70% of people who suffer from gout produce too much uric acid and 30% cannot efficiently eliminate it from their body. Elevated levels of uric acid in the body can also be an indicator of poor kidney function.


How frequent are gout attacks?

Gout attacks can recur from time to time in the same joint. The initial attack may last several days to two weeks unless treated. Over time, gout attacks may occur more often, involve more joints, have more severe symptoms and last longer.


Who is affected by gout?

Gout affects millions of people, mostly men over the age of 30, people who are overweight and people who frequently drink alcohol. When gout affects women, it is usually after menopause.


Can gout be treated through diet?

Through the specially formulated PhytoSun® food guide, uric acid levels can be controlled and by limiting certain foods, production of uric acid can be lowered.


Why do I need to urinate more often while taking the PhytoSun® Gout Atomiser?

The PhytoSun® Gout formula contains natural diuretics, which aid in flushing excess uric acid from the body.


My gout symptoms eased when first taking the PhytoSun® Gout Atomiser but after a while the pain in my joints returned. Why?

The PhytoSun® gout atomiser is specifically formulated to dissolve acidic crystals that cause the pain associated with gout. As the crystals start to dissolve they begin to shift causing a certain amount of pain. The pain will ease with continued use of the PhytoSun® Gout Atomiser.


How long will I need to take the PhytoSun® Gout Atomiser?

It is recommended that the first bottle be taken as directed and the course completed. This will ensure that all excess uric acid levels are flushed out of the system and that acidic crystals begin to dissolve. The severity of the acidic crystal build will dictate whether another full course of the formula needs to be taken or not. It is best to contact PhytoSun® directly to discuss your gout history and severity
