What parts of this plant are used medicinally?

This plant Hydraengea chinensis is used medicinally through its leaves and roots. The dried leaves are frequently prepared as a tea to help treat various ailments such as fever and inflammation. Meanwhile, the roots are often processed into decoctions to address digestive issues or to reduce swelling. Both parts contain specific bioactive compounds that contribute to their therapeutic properties in traditional practices. These components work together to provide a wide range of health benefits when used correctly.

According to a study published by "Journal of natural products", the leaves of Hydrangea chinensis were used to isolate a new secoiridoid glycoside called hydrachoside A (1). Along with this new compound, 14 known compounds were also isolated from the leaves. The study determined the absolute stereochemistry of the side chain attached to C-15 on the secoiridoid glycoside hydrangenosiade E (2). Furthermore, the previously reported structure hydrachine A (3) was revised as its epimer, (-)-neodichroine (4), which is a new compound.

What side effects this plant can have?

This plant can cause nausea, vomiting, diarrhea, abdominal pain, dizziness, confusion, seizures, and cardiac arrhythmias when ingested. The presence of cyanogenic glycosides within the leaves and stems allows the plant to release cyanide upon consumption. These toxins disrupt cellular respiration and lead to significant gastrointestinal distress. As toxicity levels increase, the central nervous system becomes severely affected, resulting in mental disorientation and convulsions. In the most critical cases, the heart rhythm becomes unstable, which can lead to fatal outcomes.

The main side effects this plant can have are shown in the list below.

  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain
