Dried cinnamon, also known as longan meat, is a medicinal drug. Women who eat longan meat every day have the benefit of tonifying the heart and spleen and benefiting qi and blood. The downside is that taking it every day may cause fire, which may cause symptoms such as heartburn and dryness. Longan meat can tonify the heart and spleen (tonifying the heart and spleen with nourishing drugs), can benefit qi and calm the mind, and can be used for those with heart and spleen qi deficiency and restlessness of the heart and mind, and is often paired with ginseng, angelica, and sour jujube kernel. It is often used with ginseng, Angelica sinensis, and Cornus officinalis to treat heart deficiency and anxiety (violent heartbeat and panic), and is often used with jujube seed, cypress seed, and cornelian cherry; and it is often used with jujube and round-grained rice for those who are weak and deficient in qi and blood after an illness or in old age. It should be noted that longan meat is contraindicated for those who are full of dampness (too much dampness causing fullness and discomfort in the spleen and stomach) or who have stopped drinking (water stays in the body), phlegm, or fire. If you need to take Longan meat to treat diseases, it is recommended to do so under the guidance of a doctor.
