Introduction
Generally speaking, there is no specific saying that "three types of people cannot consume white mulberry root (bai mao gen)." However, individuals allergic to white mulberry root, those with deficiency-cold in the spleen and stomach, excessive internal heat due to yin deficiency, impaired kidney function, and pregnant women are advised not to consume white mulberry root. These groups should be clear about their own contraindications to avoid physical discomfort caused by consumption. Other populations should also follow medical advice and control the quantity when consuming white mulberry root.

Generally speaking, there is no saying that "three types of people cannot consume Imperata root (bai mao gen)." However, individuals allergic to Imperata root, those with spleen and stomach deficiency-cold, yin deficiency with fire hyperactivity, kidney insufficiency, pregnant women, and similar individuals are not advised to take Imperata root. Detailed explanations are as follows:

1. Individuals allergic to Imperata root: After consuming Imperata root, the immune system of these individuals may mistakenly identify certain plant components in it, triggering an allergic reaction. Common symptoms include skin rashes, itching, hives, and some individuals may experience sneezing or a runny nose. Severe reactions may include laryngeal edema, difficulty breathing, and threats to health.

2. Individuals with spleen and stomach deficiency-cold: Imperata root has a cold nature and possesses heat-clearing and diuretic properties. Individuals with spleen and stomach deficiency-cold already have weak digestive function and excessive internal coldness. Consuming Imperata root could further intensify the cold nature of the spleen and stomach, potentially causing discomfort symptoms such as abdominal pain, diarrhea, loose stools, and loss of appetite, affecting the normal digestive and transformative functions of the spleen and stomach.

3. Individuals with yin deficiency fire hyperactivity: Individuals with yin deficiency fire hyperactivity often exhibit symptoms such as dry mouth and throat, heat in the palms and soles, feverish sensations, and night sweats. These individuals have insufficient body yin fluids and internal disturbance from deficient fire. The primary effect of Imperata root is clearing heat and resolving dampness, without nourishing yin properties. Consumption may consume the body's yin fluids, worsening symptoms of yin deficiency fire hyperactivity, and being detrimental to improving the body's condition.

4. Individuals with kidney insufficiency: Imperata root has a strong diuretic effect. Individuals with kidney insufficiency have reduced kidney metabolic and excretory functions. Excessive consumption of Imperata root may increase the filtration burden on the kidneys, potentially worsening kidney function damage. It may also cause electrolyte disturbances due to excessive diuresis, leading to symptoms such as fatigue and arrhythmia.

5. Pregnant women: Pregnant women have a special physical condition; the cold nature and diuretic effect of Imperata root might affect fetal stability. Particularly during early pregnancy when fetal development is not yet stable, consumption may increase the risk of abdominal pain and diarrhea, and even affect normal fetal development. Therefore, pregnant women are advised not to consume Imperata root.

The above-mentioned groups should clearly understand their contraindications to avoid physical discomfort caused by consuming Imperata root. Other individuals should also follow medical advice regarding the dosage when consuming it, avoiding long-term or excessive consumption to ensure medication safety.
