Dried cinnamon has the effect of calming the spirit and nourishing the blood, tonifying the heart and spleen. Drinking it in water has limited active ingredients and generally does not have a therapeutic effect. Dried gui yuan is longan meat, the medicinal part of the aril, sweet and warm, attributed to the spleen meridian of the foot Taiyin and the heart meridian of the hand Shaoyin. It can calm the spirit, nourish blood, and tonify the heart and spleen. It is used in the treatment of blood deficiency and atrophy, deficiency of qi and blood, palpitations and forgetfulness and insomnia. As this drug can benefit qi and blood, tonify the heart and spleen, and calm the mind, it is neither congested nor overly nourishing, and is therefore a good tonic. Longan meat is often combined with Angelica sinensis and jujube nut in tonics such as Guisheng Tang, or used alone. Longan meat should not be used in patients with phlegm, fire, stagnant fluid (water retained in the body), or Dampness in the center (Dampness that causes fullness and discomfort in the spleen and stomach). Adverse reactions are not known. Therefore, when taking Longan Pork, it is recommended to consult a physician in advance to determine whether it is appropriate to take it, so as to avoid delays.
