Although not well studied in humans, perilla may lower HDL-cholesterol levels. Caution is advised in patients with high cholesterol or those taking any cholesterol-lowering agents.
Theoretically, perilla may suppress indomethacin-induced effects, due to a change in fatty acid and eicosanoid status. Caution is advised in patients taking indomethacin or other non-steroidal anti-inflammatory drugs (NSAIDS).
Perilla frutescens may contain sedative constituents, and may interact with other herbs that have sedative properties. Drowsiness or sedation may occur. Use caution if driving or operating heavy machinery.
Theoretically, the results from an animal study suggest that the combination of perilla and beta-carotene may reduce the risk of colon cancer.
Theoretically, perilla may lower HDL-cholesterol levels. Caution is advised in patients with high cholesterol or those taking any cholesterol-lowering agents, such as red yeast rice.
Theoretically, use of fish oil or omega-3 fatty acid sources (flax oil, walnut oil, soybean oil) and perilla oil would increase omega-3 fatty acid status of blood and tissues to a greater effect than either alone. Caution is advised.
