Known hazards of Aristolochia reticulata:

We have no specific details for this species but most members of this genus have poisonous roots and stems. The plant contains aristolochic acid, this has received rather mixed reports on its toxicity. According to one report aristolochic acid stimulates white blood cell activity and speeds the healing of wounds, but is also carcinogenic and damaging to the kidneys. Another report says that it is an active antitumour agent but is too toxic for clinical use, causing gastric irritation and, in large doses, respiratry failure. Another report says that aristolochic acid has anti-cancer properties and can be used in conjunction with chemotherapy and radiotherapy and that it also increases the cellular immunity and phagocytosis function of the phagocytic cells.
