Noni Overview
Noni (Morinda citrifolia) is a tropical fruit that is native to Southeast Asia and the Pacific Islands. It is also known by a variety of other names, including Indian mulberry, beach mulberry, and cheese fruit. Noni fruit is typically not eaten fresh due to its strong flavor and smell. Regardless, many parts of the plant, including the roots, fruit, stem, bark, leaves, and flowers are used to make juice, supplements, and other products.
Noni has a long history of use in traditional medicine. Some studies have suggested that noni may have potential health benefits, including the ability to reduce inflammation, improve immune function, and lower blood pressure. It is also thought to have antioxidant and anti-tumor effects.
Carbidopa, Levodopa Overview
-
The combination of levodopa and carbidopa is used to treat the symptoms of Parkinson's disease and Parkinson's-like symptoms that may develop after encephalitis (swelling of the brain) or injury to the nervous system caused by carbon monoxide poisoning or manganese poisoning. Parkinson's symptoms, including tremors (shaking), stiffness, and slowness of movement, are caused by a lack of dopamine, a natural substance usually found in the brain. Levodopa is in a class of medications called central nervous system agents. It works by being converted to dopamine in the brain. Carbidopa is in a class of medications called decarboxylase inhibitors. It works by preventing levodopa from being broken down before it reaches the brain. This allows for a lower dose of levodopa, which causes less nausea and vomiting.
