HemoHIM and Medications: Interactions, Blood Thinners and What to Ask Your Doctor
Can you take HemoHIM with medication? No study has tested HemoHIM together with any medicine, so the risk is unknown rather than zero. Here is what is known about its herbs, blood thinners, immunosuppressants and what to ask your doctor.
Short answer: no study has ever tested HemoHIM together with any medicine. That means the interaction risk is unknown — not proven to be zero. If you take prescription medicines, especially blood thinners, immunosuppressants or medicines for a serious chronic condition, talk to your doctor or pharmacist before you start HemoHIM.

What the official label says
The Korean product information for HemoHIM lists these cautions: it is not recommended for children or for pregnant or breastfeeding women; people with irregular menstruation or a bleeding disorder, and people taking anticoagulants (blood thinners), should consult a professional first; allergic reactions are possible; and anyone who has an adverse reaction should stop and seek advice.
Blood thinners (warfarin, antiplatelet drugs)
In laboratory and animal studies, extracts and compounds from Angelica gigas — the main herb in HemoHIM — reduced platelet clumping. This has not been shown in people, but it may be one reason the label tells people on anticoagulants to consult a professional first.
Do not confuse Angelica gigas (Korean angelica) with Angelica sinensis (dong quai). The well-known warfarin warning is for dong quai, a different species. That warning does not automatically apply to HemoHIM — but it also does not mean Angelica gigas is proven safe with warfarin.
Liver enzymes that process medicines
Laboratory studies show that decursinol angelate, a compound from Angelica gigas, can inhibit CYP2A6, a liver enzyme that breaks down some medicines, and that Angelica gigas compounds are themselves processed by the enzymes CYP2C19 and CYP3A4. These are test-tube findings; whether HemoHIM at normal intake changes medicine levels in people has never been studied.
Immunosuppressants, autoimmune disease and transplants
HemoHIM is studied for its effect on the immune system. For other immune-active herbs, such as astragalus and echinacea, cancer and integrative-medicine centres warn that they may work against immunosuppressant medicines. HemoHIM has not been tested with these drugs, but if you have had an organ transplant, have an autoimmune disease or take immunosuppressants, do not take HemoHIM without your specialist’s approval.
Cancer treatment
Animal studies have looked at HemoHIM alongside radiation or chemotherapy, but there are no human studies on combining it with cancer treatment. Always ask your oncology team before taking any supplement during treatment. See HemoHIM and cancer research.
The 2021 Hong Kong cases and methoxsalen As of October 2026, HemoHIM is sold again in Atomy’s Singapore mall and, as HemoHIM G (艾多美 煥力飲G), in Atomy’s Taiwan mall; it is still not sold in Hong Kong.
In 2021 Hong Kong authorities found methoxsalen, a prescription drug that makes the skin more sensitive to sunlight and can affect the liver, in HemoHIM samples after four liver-injury cases. A 2023 Korean review noted that the patients were also taking other medicines, some of them linked to liver injury, and argued that the cause was not established. Either way, it is one more reason to tell your doctor about every supplement you take. Details in Is HemoHIM banned?.
What to ask your doctor or pharmacist
- “I want to take HemoHIM, a herbal extract of Angelica gigas, Cnidium officinale and peony root, one sachet twice a day. Is that compatible with my medicines?”
- Bring the product or a photo of the label to the appointment.
- Ask whether any blood tests (for example clotting tests or liver tests) should be checked after you start.
- Stop HemoHIM before surgery if your doctor advises it, and tell the surgical team you have been taking it.
The US National Center for Complementary and Integrative Health advises telling all your health care providers about every supplement you use, because “natural” does not mean free of interactions. For more on safety, read our HemoHIM side effects guide and HemoHIM and the liver.
❓ Can I take HemoHIM with my medication?
No study has tested HemoHIM with any medicine, so the risk is unknown. Ask your doctor or pharmacist first, especially if you take blood thinners, immunosuppressants or medicines for a chronic condition.
❓ Can I take HemoHIM with warfarin or other blood thinners?
Only after talking to your doctor. The official label advises people taking anticoagulants to consult a professional, and Angelica gigas compounds reduced platelet clumping in lab and animal studies.
❓ Is HemoHIM the same as dong quai?
No. HemoHIM contains Angelica gigas (Korean angelica). Dong quai is Angelica sinensis, a different species with its own known warfarin warning.
❓ Can I take HemoHIM after an organ transplant or with an autoimmune disease?
Not without your specialist’s approval. HemoHIM is studied for immune effects and has not been tested together with immunosuppressant medicines.
