You’ve probably heard of neuro-toxins, those pollutants such as pesticides that can interfere with nerve function (and therefore are very bad for brain health). If you suspect that you may have been exposed to dangerous fumes or toxic chemicals, consult a doctor for a thorough analysis and treatment. To cleanse your brain (and your body) of common toxins, such as pollutants or household chemicals, you can try a variety of natural remedies. These include flaxseed, licorice root, ginseng, ginkgo biloba, aloevera, grapefruit pectin, papayas, slippery elm bark, alfalfa, peppermint, and ginger tea. You can take capsules or use the ingredients to make tea. You can also drink lemon water, exercise strenuously, use a sauna, get a vigorous massage, and eat a high-fiber, cleansing diet. Deep breathing exercises, in clean environments, will infuse your brain with fresh oxygen. When it comes to minimizing food contaminants, wash all fruits and vegetables thoroughly.
