Introduction
Under normal circumstances, it is not recommended to take Polygonum multiflorum (He Shou Wu) during menstruation. Polygonum multiflorum is categorized into raw and processed forms. Although processing reduces its toxicity, the processed form possesses strong nourishing properties that may hinder the smooth discharge of menstrual blood, particularly in individuals with light menstrual flow or dysmenorrhea, potentially worsening their symptoms. According to traditional Chinese medicine, excessive nourishing or astringent herbs should be avoided during menstruation to prevent disruption of the balance in qi and blood circulation.

Generally speaking, it is not recommended to take Polygonum multiflorum (He Shou Wu) during menstruation. The detailed explanation is as follows:

  

There are two forms of He Shou Wu: raw and processed. Although the toxicity of processed He Shou Wu is reduced, it has strong nourishing properties that may hinder the smooth discharge of menstrual blood. It could potentially worsen symptoms for women with light menstrual flow or dysmenorrhea. Traditional Chinese Medicine (TCM) advises against excessive nourishing or astringent herbs during menstruation, as they may disrupt the balance of qi and blood circulation. Raw He Shou Wu has certain toxicity and is primarily used for lubricating the intestines and relieving constipation; taking it during menstruation might irritate the intestines or interfere with the normal menstrual cycle.

If He Shou Wu is taken together with other medications such as aspirin or hormonal contraceptives, it may cause interactions. Individuals with allergic constitutions should be cautious about possible adverse reactions like rashes or gastrointestinal discomfort. If symptoms such as prolonged menstruation, aggravated abdominal pain, or dizziness occur during use, discontinue immediately. Women with a naturally "hot" constitution or heavy menstrual flow should be particularly cautious, as the warming and nourishing properties of He Shou Wu may lead to blood heat or abnormally increased menstrual flow.

Therefore, whether or not to use He Shou Wu during menstruation should be determined based on individual constitution and health conditions. If there are special needs or concerns, it is advisable to consult a TCM practitioner or gynecological specialist for personalized guidance. Additionally, in daily diet, it is important to maintain balanced nutrition, avoid excessively cold or spicy foods, and maintain healthy lifestyle habits to support overall well-being.
