  • The oil increases the risk of bleeding , so it should be avoided by those taking anticoagulants or antiplatelets, as it enhances the effects of these drugs.
  • The oil enhances the positive and negative effects of antiretrovirals , so those who follow a treatment with this type of drug may suffer its adverse effects with greater intensity.
