Please note that I am not a doctor and cannot provide personalized medical advice. If you or someone close to you is experiencing more severe anxiety or other mental health issues, it is best to consult a medical professional or mental health expert. Generally speaking, there are currently no rigorous clinically proven over-the-counter drugs that can "quickly" relieve anxiety. Most drugs approved by the FDA or other authoritative agencies for anxiety (such as benzodiazepines, SSRIs, etc.) require a prescription, and these drugs should be evaluated and supervised by a professional doctor based on individual circumstances. However, some people choose to use some over-the-counter herbal or nutritional supplements in the hope that they can have a certain auxiliary effect on anxiety and stress. From the common products on the market, the following categories are often mentioned, but their effects, speed of action and safety vary from person to person, and the research results are also controversial: 1. Valerian Root: Some people believe that it helps relax nerves and improve sleep, but there is no sufficient scientific evidence to support its effect of "quickly" relieving anxiety. 2. L-Theanine: Commonly found in green tea, some studies have shown that it may help relax and balance emotions, but it usually takes a period of continuous use to play an auxiliary role. 3. Chamomile: It is often used in the form of tea to help relieve mild anxiety and improve sleep, but its effectiveness in quickly relieving severe anxiety symptoms in the short term is uncertain. 4. Other herbal products and adaptogens (such as aloe vera, Morinda officinalis, Ayurvedic formulas, etc.): There are many comprehensive formulas on the market that focus on "reducing anxiety", but their ingredients, dosages and clinical verification vary greatly. In terms of purchasing channels: • Most health food stores, pharmacies or supermarkets may sell the above herbs and nutritional supplements; • Many online retail platforms (such as Amazon, iherb, etc.) also provide various products, but when purchasing, you should choose a reputable seller and pay attention to the production standards and approval numbers of the products; • Note that different countries and regions may have different regulatory policies and sales regulations for certain herbal products. It is important to emphasize that: • OTC supplements are generally not subject to the same strict regulation as prescription drugs, so product quality, purity, and dosage may vary; • If you are taking other medications or have special health problems, some herbal products may cause drug interactions or side effects; • For acute anxiety or severe emotional distress, trying OTC products on your own may not achieve the desired effect, so it is important to get professional help in a timely manner. In short, if you are considering using OTC products as an auxiliary way to regulate your emotions, it is recommended that you first consult a doctor or pharmacist to understand whether they are suitable for your specific situation and master the correct usage and dosage.
