Can Ophiopogon japonicus be eaten raw?
Generally speaking, Ophiopogon japonicus (McDoor) can be eaten directly, but it should be taken under the guidance of a physician. The detailed explanation is as follows:

Dried Ophiopogon japonicus can be washed and chewed directly. It has a slightly sweet and moist taste, and its refreshing and moist flavor is slowly released during chewing. Eating it directly allows the body to absorb its nutrients more directly. When experiencing dry mouth or throat discomfort, chewing a small amount can help relieve these symptoms and provide additional hydration to the body. This is a simple and convenient method of consumption.
However, there are some precautions to note when consuming Ophiopogon japonicus directly. The quantity consumed each time should not be excessive, as overconsumption may increase the digestive burden on the body. It is generally recommended to consume only a few pieces at a time. People with weak spleen and stomach function or those prone to bloating and diarrhea should consume it cautiously to avoid worsening these symptoms. If any physical discomfort occurs after consumption, usage should be stopped immediately, and professional advice should be sought if necessary.
