The main components include tanshinone and notoginsenoside, which have functions of promoting blood circulation, removing blood stasis, and improving myocardial blood supply. It is generally considered relatively safe, but there are still some potential side effects:

1. Gastrointestinal symptoms: Some patients may experience nausea, vomiting, abdominal pain, stomach distension, and other gastrointestinal symptoms. These symptoms might be caused by the drug's irritation to the gastrointestinal tract or by inducing central nervous system dysfunction.

2. In rare cases, severe adverse reactions such as anaphylactic shock or liver function damage may occur, although these are uncommon.

3. Neurological symptoms: Some patients may experience symptoms such as headache and dizziness. Headache may be caused by vasodilation or increased neurotransmitter release induced by the drug's components. Dizziness may result from the drug affecting vestibular system function or fluctuations in blood pressure.

It is recommended to use this medication under the guidance of a physician. If any of the above adverse symptoms occur, the medication should be discontinued promptly and medical attention sought.
