Cooked Rehmannia root is a commonly used traditional Chinese herb known for its functions of nourishing essence and marrow, enriching blood, and replenishing Yin. It is frequently used to alleviate symptoms such as kidney deficiency and anemia. Boiling it in water for consumption is a common method of administration, effectively releasing its medicinal properties. Cooked Rehmannia root water is suitable for individuals experiencing symptoms such as blood deficiency with pallor, dizziness, palpitations, insomnia, and irregular menstruation. However, it is not recommended for those with weak spleen and stomach, Qi stagnation with excessive phlegm, abdominal distension, poor appetite, or loose stools.
Cooked Rehmannia root can be combined with other herbs to enhance its therapeutic effects. When paired with herbs such as Angelica sinensis (Dang Gui) and Chuanxiong (Ligusticum wallichii), its blood-nourishing and blood-activating effects can be enhanced. However, it should not be taken together with radish,薤白 (Allium chinense),韭白 (garlic chives), or Perilla, as these may interfere with its efficacy. Pregnant women, lactating mothers, and individuals with other medical conditions should use it only under the guidance of a physician. During the consumption of cooked Rehmannia root, it is advisable to avoid raw, cold, spicy, or otherwise irritating foods.
While taking cooked Rehmannia root, it is important to take the appropriate dosage and follow medical advice. Do not increase the dosage or prolong the duration of use on your own to avoid unnecessary harm to the body. If discomfort occurs after taking cooked Rehmannia root, seek medical attention promptly and follow the physician's instructions for treatment.
