Dong Quai and Fish Oil: what the published research says

PubMed indexes 4 records that name Dong Quai and Fish Oil together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Dong Quai and Fish Oil. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

4 studies naming Dong Quai and Fish Oil.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

The Extract of Angelica sinensis Inhibits Hypoxia-Reoxygenation and Copper-Induced Oxidative Lesions and Apoptosis in Branchiae and Red Blood Corpuscles of Fish.

Veterinary sciences · 2023 · PMID 38275917

“The present results suggested that dietary AsE improved hypoxia tolerance and inhibited HR or Cu-triggered oxidative lesions and apoptosis. Therefore, AsE can be utilized as a natural inhibitor of Cu and HR stress in fish.”

Long et al. · From the abstract

Names both Dong Quai and Fish Oil in its title.

Integrated biomarker parameters response to the toxic effects of high stocking density, CuSO(4), and trichlorfon on fish and protective role mediated by Angelica sinensis extract.

Fish physiology and biochemistry · 2020 · PMID 32557080

Randomized Controlled Trial, VeterinaryAnimal study

“However, dietary EAs improved muscular function and inhibited oxidative damage via quenching ROS and elevating non-enzymatic and enzymatic antioxidant activity in muscles of trichlorfon-induced fish. So, EAs could be used as an inhibitor of high density, CuSO4, and trichlorfon stress in fish.”

Li et al. · From the abstract

Names both Dong Quai and Fish Oil in its title.

The effects of ethoxyquin and Angelica sinensis extracts on lipid oxidation in fish feeds and growth, digestive and absorptive capacities and antioxidant status in juvenile red carp (Cyprinus carpio var. xingguonensis): a comparative study.

Fish physiology and biochemistry · 2019 · PMID 29980882

Clinical Trial, VeterinaryAnimal study

“However, dietary EQ inhibited the digestive, absorptive and antioxidant capacities in fish. So, EAE could be used as a natural antioxidant for replacing EQ in fish feeds.”

Li et al. · From the abstract

Names both Dong Quai and Fish Oil in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Dong Quai, Fish Oil, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
