Radix Rehmanniae (Shu Di Huang) is a traditional Chinese medicinal herb that can also be used in cooking. Many people incorporate Radix Rehmanniae into their diet, but it is important to consume it in moderation, especially considering its medicinal properties. So, how much Radix Rehmanniae should be used?
Recommended Dosage of Radix Rehmanniae
The recommended dosage of Radix Rehmanniae is 10-30 grams.
Typically, Radix Rehmanniae is used in a dosage of 10-30 grams. It has no significant toxic side effects and can be adjusted based on the individual's condition. However, excessive consumption is not advisable. Radix Rehmanniae has a sticky texture, and if taken in excess, the body may not fully absorb its medicinal effects, which can negatively impact digestion.
What Happens If You Consume Too Much Radix Rehmanniae?
Due to its sticky nature, excessive consumption of Radix Rehmanniae is not recommended. Additionally, individual reactions to medications can vary. Here are a few possible symptoms of consuming too much Radix Rehmanniae:
Digestive Issues
Some individuals may experience discomfort such as bloating, loss of appetite, and aversion to food due to the sticky nature of Radix Rehmanniae, which can make it difficult for the intestines to digest.
Diarrhea and Abdominal Pain
Radix Rehmanniae contains polysaccharides, catalpol, and mannitol. Some individuals may experience allergic reactions such as abdominal pain, diarrhea, itching, and skin rashes when consuming excessive amounts of Radix Rehmanniae.
Phlegm Accumulation and Qi Stagnation
Excessive consumption of Radix Rehmanniae, which has a sticky nature, may lead to symptoms such as excessive phlegm in the throat, palpitations, fatigue, and chest tightness.
What to Do If You Consume Too Much Radix Rehmanniae
1. Stop Consuming Radix Rehmanniae Immediately
If the symptoms are mild, simply stopping the consumption of Radix Rehmanniae for a period of time should alleviate the discomfort.
2. Drink Plenty of Water
Drinking plenty of water after consuming too much Radix Rehmanniae can help dilute its concentration in the body and alleviate the symptoms to some extent.
3. Induce Vomiting
If the symptoms include abdominal pain, nausea, or itching, inducing vomiting can help prevent the symptoms from worsening to a certain extent.
4. Seek Medical Attention
If the symptoms are severe or include palpitations, shortness of breath, or other discomfort, immediate medical attention should be sought to receive appropriate treatment, such as detoxification and fluid replacement, to prevent further complications.
Can Radix Rehmanniae Be Consumed Long-Term?
In general, it is not recommended to consume Radix Rehmanniae long-term.
Due to its sticky nature and poor digestibility, long-term consumption of Radix Rehmanniae may hinder normal digestion and affect the functioning of the spleen and stomach.
If long-term consumption is necessary for the treatment of a specific condition, it is advisable to consult a doctor and combine Radix Rehmanniae with other herbs that help tonify the spleen and stomach, such as dried tangerine peel and sandalwood.
Precautions When Consuming Radix Rehmanniae
Avoid Using Iron Utensils When Preparing Radix Rehmanniae
According to the book "Ya Jian," "If violated with iron utensils, it will consume the kidneys." Therefore, when preparing Radix Rehmanniae, it is important to avoid using copper or iron utensils. The components in Radix Rehmanniae may react with copper or iron, reducing its effectiveness or producing substances that are harmful to the body.
Avoid Consuming Radix Rehmanniae with Radish and "Three Whites"
The book "Ben Cao Pin Hui Jing Yao" states, "Avoid radish, white onion, white leek, and white shallot." Radish has the effect of reducing qi, and the "Three Whites" have a strong dispersing effect. Consuming Radix Rehmanniae in combination with these ingredients may reduce its nourishing effects.
Who Should Avoid Consuming Radix Rehmanniae?
1. Individuals with Weak Spleen and Stomach
Individuals with weak spleen and stomach should avoid consuming Radix Rehmanniae as it may worsen symptoms such as abdominal distension, loss of appetite, pale complexion, and loose stools.
2. Individuals with Qi Stagnation and Phlegm Accumulation
Individuals with symptoms of qi stagnation and phlegm accumulation should avoid consuming Radix Rehmanniae as its sticky nature and poor digestion may worsen phlegm-related symptoms such as local swelling, chest tightness, rib pain, and slippery pulse.
3. Individuals with Cold or Flu
Radix Rehmanniae is considered a nourishing herb in traditional Chinese medicine, and it is believed that during a cold or flu, it is not advisable to tonify the body. Consuming Radix Rehmanniae during this time may worsen cold or flu symptoms or prolong the duration of illness.
4. Individuals with Loose Stools or Diarrhea
Individuals with loose stools or diarrhea should avoid consuming Radix Rehmanniae as its sticky nature may hinder the digestive function of the spleen and stomach, worsening the symptoms.
