Are there alternative treatments for stagnant anoxia?

Because stagnant anoxia immediately deprives organs or tissues of needed oxygen, the only immediate treatment is a supplement of pure oxygen. However, there are alternative treatments for some of the causes of stagnant anoxia. Studies are being conducted on how garlic, flaxseed, and omega-3 fatty acids supplements can aid in combating cardiovascular disease. According to the National Center for Alternative and Complimentary Medicine, some alternative practitioners also recommend plant-based medicines containing hawthorn or astragalus to fight heart disease.
