Well said.
As I said, any such claim in the (historic) literature, needs to be verified.
Science had a kind of glory-era, in which many things were put to experimental tests. This included many folk remedies, and the results of which became modern medicines. Take for instance, aspirin, which comes from a summer tea. (not really willow bark, aspirin was actually synthesized from a different remedy, that just so happens to also contain salicylic acid. Specifically meadowsweet. The A in Aspirin is for Acetyl, and the Spirin is for Spiraea ulmaria, the botanical name for meadowsweet.)
Some old remedies were in fact, quite effective, but carried risk factors, or other comorbidities from use, that made them less desirable than other remedies, and as science zeroed in on the best, and safest ones, they fell by the way side.
In this particular instance, I think it would be advantageous to remember that older methods exist, and what their risk factors are, in light of the fact that back-alley abortions are GOING to become things again. Its not hard to justify spreading awareness of that knowledge, when the thing you are competing against is a goddamn coat hanger. You aren't competing with modern medicine-- hands down, modern medicine is the best there is, and the best that can be provided--- the problem is that people are being actively DENIED that. Instead, you are competing against dangerous shit like gorging on OTC medications, or using coat hangers. If your risk factors are less severe than the consequences of those, and the preparation is effective, it has a valid use.
(and, for your convenience of knowing, Foxglove was administered for high blood pressure, and edema from congestive heart failure.
It *WAS* effective. However, the useful dosages were dangerously close to toxic dosages, and the potency of the individual plants is difficult to assay. It was one of the "oh yes, it totally DOES in fact work" remedies that fell by the wayside, as superior medications that are easier to dose, and less likely to cause accidental poisoning were identified, and means of synthetic (and thus highly pure) synthesis discovered. )
