How should ginkgo leaves be processed in order to steep them in water for consumption?

　　Ginkgo leaves generally need to be processed through steps such as washing the leaves, removing impurities, air-drying, appropriate crushing, and controlling the dosage before being used for brewing in water. If in doubt, it is recommended to consult a healthcare professional beforehand. Detailed explanations are as follows:

　　1. Washing the leaves: After harvesting or purchasing ginkgo leaves, they should be thoroughly washed with clean water to remove surface dust and impurities. This step ensures the safety of subsequent consumption and prevents harmful substances from entering the body.

　　2. Removing impurities: After washing, inspect the ginkgo leaves and remove any withered leaves, insect-damaged leaves, or other foreign materials. Ensuring the integrity and purity of the leaves is the foundation for making high-quality ginkgo leaf tea.

　　3. Air-drying: Cleaned ginkgo leaves should be naturally dried in a well-ventilated, shaded area or processed using low-temperature drying equipment. Dried leaves are easier to store and help preserve their active components for later brewing.

　　4. Appropriate crushing: Dried ginkgo leaves can be slightly rubbed or crushed to facilitate the release of active substances. However, they shouldn't be ground too finely, as this may affect filtration and taste during brewing.

　　5. Controlling the dosage: Ginkgo leaves contain certain toxic components, so the dosage must be strictly controlled when preparing the water infusion. Generally, it is recommended to use only a few leaves per use to avoid adverse reactions such as abdominal pain or diarrhea due to excessive consumption.

　　When brewing ginkgo leaves in water, they can be combined with other mild herbal ingredients or food materials, such as wolfberry or chrysanthemum, to enhance flavor and efficacy. However, avoid mixing with strongly stimulating herbs to prevent potential adverse effects on health.
