How to use it as medicine, and the dosage—whether to swallow it raw, press it into juice, dry it and boil it into a medicinal soup, or directly inject it into the veins—is something that Austin, who is essentially illiterate in traditional Chinese medicine, has no idea about.
Even though, theoretically, these plants can grow inside the Spider Cave and have a high chance of neutralizing the poison produced by the spiders, figuring out how to enable those substances to work in Rodney and others' bodies without harming them is indeed a profound and complex field of study.
However, under the current circumstances, there is no way for Austin to spend a year or two exploring this; otherwise, Rodney's grave would probably have grass several meters high by then, and even if he managed to gather experience, what use would it be?
There's no choice but to take measures one by one.
