Thai food is well known around the world because of its taste and nutritional values. Many researchers found that Thai food provides high nutrition with health benefits. In the past, before the medicine was widely available in Thailand, Thai people used Thai herbs to treat some illnesses. Garlic, for example, helps reduce blood pressure. Shallot eases cold symptoms. Chili stimulates blood circulation. Lemongrass relieves digestive disorders and increases urine flow. Galangal, meanwhile, eases gastrointestinal discomfort.
