Lysimachia christinae is a poison to people, but it does have magical effects in raising pigs.

When the gastrointestinal function of pigs is poor, we can feed pigs with intestinal parasites for a period of time, thus increasing their appetite, promoting their growth and increasing their weight. But it can't be used on pregnant sows, and its toxicity is likely to harm the fetus. A little careless dosage may cause deformity, premature delivery, stillbirth and even abortion.
