My Friend Bought a “Blood Stasis Paste” for Her Thyroid Nodule. I Told Her to Wait.

At ten p.m., a friend sent me a photo of her health check report. Thyroid nodule, TI-RADS 4a. Below it: “I bought Blood Stasis Paste. Can I take it?”

I told her not to open the package yet. Turn to the last page of the ultrasound report and look at the classification. Find the thyroid function tests and look at TSH, FT3, FT4. Write down the date of your last period. Then make an appointment with endocrinology. She replied “Okay,” then added, “Isn’t it blood stasis?”

I have heard this sentence many times in the past year.

The words on health check reports are increasing: thyroid nodules, breast nodules, uterine fibroids, ovarian cysts, ovarian masses. They crowd onto one A4 page like a string of unfamiliar place names. Some people search for “nodule-dissolving tea” right after reading it. Some buy “stasis-resolving paste.” Some shove the report into a drawer.

These words are not one disease.

A thyroid nodule is a lump in the thyroid. A breast nodule is a localized change on breast imaging. A uterine fibroid is a benign overgrowth of uterine smooth muscle. An ovarian mass may be a physiological cyst, a chocolate cyst, a teratoma, or something else. Their causes differ, their follow-up intervals differ, and their management differs. Calling them all “blood stasis” is understandable in a TCM context. It cannot replace diagnosis in modern medicine.

TCM has its own logic for blood stasis. Qi is the commander of blood; blood is the mother of qi. When qi moves, blood moves. When qi stagnates, blood stasis forms. Cold congelation slows blood. Qi deficiency means blood cannot be pushed. Qi stagnation makes blood flow unsmooth. Phlegm-dampness binds with stasis. Over time, the meridians are blocked, and locally there may be “zheng jia,” “ji ju,” or “pi kuai.” Wang Qingren wrote in Yi Lin Gai Cuo about Xuefu Zhuyu Tang, with a mnemonic line: “When blood is transformed and moves downward, it will not cause consumptive disease.” Zhang Xichun said in Yi Xue Zhong Zhong Can Xi Lu about hawthorn: “It is good at entering the blood division and is an essential medicine for transforming blood stasis. It can eliminate xuan pi zheng jia, amenorrhea in women, and postpartum blood stasis pain.”

“Zheng jia” and “ji ju” in ancient texts describe a category of patterns, including abdominal masses, menstrual blockage, and postpartum stasis pain. They cannot be directly equated with malignant tumors. “Transforming stasis” in TCM is also not simply dissolving a tumor.

Blood stasis can be a perspective for understanding the body. It is not the final explanation on a health check report.

Tongue inspection can suggest blood stasis. Lower your head, stick out your tongue, and see whether the tongue body is dark, purplish, or bluish, and whether there are purple spots or dots on the tip or edges. Then look at the two veins under the tongue and see whether they are purplish, blackish, engorged and tortuous like earthworms. These do have reference value in TCM inspection. A dark tongue body and engorged sublingual veins are often seen as clues to blood stasis.

A clue is not a diagnosis.

Tongue color is affected by age, cold, hypoxia, food coloring, smoking, and medication. How visible the sublingual veins are also depends on local anatomy and individual variation. Some people naturally have prominent sublingual veins, which does not mean they have a tumor. Some people have a normal tongue appearance and still have nodules. The tongue can remind you to pay attention. It cannot determine the nature of a nodule. To determine that, you need ultrasound, imaging, laboratory tests, and, when necessary, pathology.

Hawthorn is a medicinal and edible fruit. It aids digestion, reduces meat stagnation, and moves qi and disperses stasis. For people with food stagnation, greasy meals, high blood lipids, or a mild tendency to blood stasis, hawthorn is a good dietary aid. It is sour and sweet and nourishes yin. It moves stagnation within the blood and is not as drastic as some blood-moving medicines. It is like a patient cleaner, sweeping away fallen leaves in a riverbed bit by bit.

Hawthorn is not a demolition crew.

It cannot dissolve thyroid nodules, breast nodules, or uterine fibroids. There is no reliable clinical evidence that it can “dissolve nodules” or “eliminate tumors.” Eating a lot of hawthorn may also cause acid reflux and stomach pain. People with gastric ulcers or gastroesophageal reflux should be careful. People taking warfarin, aspirin, clopidogrel, or rivaroxaban should also note the possible increased bleeding risk.

If it is ordinary food or a health food, “Blood Stasis Paste” cannot claim to treat nodules or tumors. If it is a drug, it needs a drug approval number and medical guidance. If it contains saffron, safflower, peach kernel, angelica, astragalus, cinnamon bark, or kelp, it is not suitable for everyone.

Pregnant women, women trying to conceive, women with heavy periods, and people with bleeding tendencies should use it cautiously or not at all. People taking anticoagulants or antiplatelet drugs may have an increased bleeding risk. People with gastric ulcers, excess stomach acid, or reflux esophagitis may find hawthorn irritating to the stomach. People with thyroid nodules should be especially careful with kelp. Kelp is high in iodine. People with hyperthyroidism, Hashimoto’s thyroiditis, or a need for iodine restriction should not eat it casually. People before or after surgery, during breastfeeding, children, and people with abnormal liver or kidney function should not take it long-term on their own.

Ancient formulas used in modern ways: the idea can be borrowed, but the formula cannot be applied indiscriminately. Xuefu Zhuyu Tang is a prescription formula and requires pattern differentiation. Qi-deficiency blood stasis, qi-stagnation blood stasis, cold-congealing blood stasis, and phlegm-stasis binding require different directions of treatment. Not everyone is suitable for astragalus or cinnamon bark, and not everyone is suitable for kelp. A paste formula is not food and cannot be one formula for everyone.

If you have found a nodule, fibroid, or ovarian mass on a health check and want to approach it from a TCM angle, first ask five questions.

Have I already had a standard specialist evaluation? For thyroid nodules, look at TI-RADS and thyroid function. For breast nodules, look at BI-RADS. For gynecological problems, look at ultrasound and tumor markers. Follow up when follow-up is needed. Biopsy when biopsy is needed.

Am I taking anticoagulants or antiplatelet drugs? Warfarin, aspirin, clopidogrel, and rivaroxaban may increase bleeding risk when combined with blood-moving and stasis-transforming medicines.

Do I have a bleeding tendency or stomach disease? Heavy periods, easy gum bleeding, gastric ulcers, and reflux esophagitis are not suitable for casually taking blood-moving medicines and hawthorn long-term.

Do I have a thyroid problem? People with hyperthyroidism, Hashimoto’s thyroiditis, or a need for iodine restriction should be cautious with kelp, seaweed, and other high-iodine medicinals.

Am I pregnant, trying to conceive, or breastfeeding? Blood-moving and stasis-transforming medicines are mostly contraindicated or should be used cautiously. A doctor must be consulted.

If these five questions are not clear, do not rush to “transform stasis.”

The correct order is: first evaluate, then regulate.

For thyroid nodules, look at the TI-RADS classification on ultrasound, check thyroid function, and biopsy if necessary. For category 4 and above, specialist evaluation is especially important. For breast nodules, look at BI-RADS. For category 4 and above, bloody nipple discharge, orange-peel skin changes, or rapid growth, see a breast surgery specialist as soon as possible. For uterine fibroids, look at size, location, whether they cause heavy periods, anemia, pressure symptoms, or affect fertility. For ovarian masses, look at whether they are physiological or persistent, their ultrasound features, and tumor markers. When necessary, have a gynecological surgical evaluation.

Any nodule that rapidly enlarges in a short time, hoarseness, difficulty swallowing, weight loss, ascites, or postmenopausal bleeding should prompt a medical visit.

TCM can regulate some of this. The premise is an in-person visit for pattern differentiation and a prescription from a qualified TCM doctor. Do not buy “blood-moving and stasis-transforming paste” and take it long-term on your own. Do not delay follow-up because you are taking a paste. If you have a thyroid problem, first confirm your iodine intake strategy. If you are taking Western medicine, especially anticoagulants, ask your doctor first.

“Clearing silt” in life is not only about taking a certain medicine. Sleep deeper. Give emotions an outlet. Move your body. Lighten your diet. Keep your lower back and abdomen warm. Show up for follow-up on time. For a river to flow freely, it is not enough to dredge silt. You also need to protect the banks, plant trees, save water, and open tributaries.

Later, my friend did three things. She put the Blood Stasis Paste back in the cabinet, made an appointment with endocrinology, and put the ultrasound report and thyroid function tests into a transparent file bag. The next morning, she sent a photo: the queue screen in the hospital corridor, number A032. She said, “I’ll listen to the doctor first.”

The nodule on the health check report is not a verdict, nor is it waste paper. It is like a note the body has written in some corner: there was inflammation here, hormones affected this place, the flow of qi and blood may not be smooth here, this place needs you to look at it more.

Do what the evaluation calls for: check, treat, regulate, or wait.

Do not let a spoonful of paste, the phrase “blood stasis,” or fear stand in for an ultrasound, a specialist evaluation, or action.

Later, she did not ask again whether she could take the paste. She asked, “Is the next follow-up in three months or six months?”

The doctor gave a number. She wrote it in her phone calendar and set a reminder.

That spoonful of paste is still in the cabinet. The follow-up report is in the file bag.
