Introduction
In general, the effects and benefits of fennel mainly include warming the kidneys to dispel cold, regulating qi to harmonize the stomach, promoting digestion, relieving dysmenorrhea, and alleviating cold-induced pain. Fennel is warm in nature and should not be consumed in excess by individuals with yin deficiency and internal heat, as it may exacerbate internal heat symptoms. As a food therapy ingredient, fennel cannot replace medication for treating diseases; prompt medical attention is necessary if symptoms are severe. Individuals in special populations should consult a healthcare professional before consumption.
Generally speaking, the effects and benefits of fennel mainly include warming the kidneys to dispel cold, harmonizing the stomach and regulating qi, promoting digestion, relieving dysmenorrhea, and alleviating pain caused by cold. Detailed explanations are as follows:
1. Warming the Kidneys and Dispelling Cold
Fennel has a warm nature and a pungent flavor. It can warm and invigorate kidney yang, dispel cold pathogens in the lower jiao, and alleviate discomfort such as cold pain in the waist and knees and cold distension in the lower abdomen caused by kidney yang deficiency and cold pathogen invasion. When cold pathogens stagnate in the lower jiao, consuming fennel can help warm the kidneys and reduce discomfort caused by cold.
2. Harmonizing the Stomach and Regulating Qi
Fennel can regulate the flow of qi in the spleen and stomach, alleviating symptoms such as abdominal distension, belching, and acid regurgitation caused by disharmony of stomach qi. When qi stagnation occurs in the spleen and stomach, consuming fennel can harmonize stomach qi, improve the smooth flow of qi in the gastrointestinal tract, and relieve gastric discomfort.
3. Promoting Digestion
Fennel contains volatile oils that can stimulate the secretion of saliva and gastric juices, enhance gastrointestinal motility, accelerate food digestion and absorption, and improve conditions such as loss of appetite and indigestion. When appetite is poor, moderate consumption of fennel can stimulate appetite and promote digestive function.
4. Relieving Dysmenorrhea
Fennel can warm the meridians, dispel cold, and relieve pain, thereby alleviating dysmenorrhea and cold pain in the lower abdomen caused by cold-induced blood stasis. During menstruation, consuming fennel can help promote blood circulation and alleviate pain symptoms.
5. Dispelling Cold and Relieving Pain
Fennel can expel internal cold pathogens and alleviate pain such as cold pain in the limbs and joints and hernia pain caused by cold pathogens. When pain is caused by cold pathogens, consuming fennel can help eliminate cold and relieve pain, making the body more comfortable.
Fennel is warm in nature and should not be consumed in large quantities by individuals with yin deficiency and excessive internal heat, as it may exacerbate internal heat. As a food therapy ingredient, it cannot replace medication for treating diseases; if symptoms are severe, timely medical attention should be sought. Individuals in special populations should consult a healthcare professional before consumption.
