Significant anti-inflammatory effects were also observed with administration of 32 mg/kg lignum vitae extract. In the acute toxicity test, no signs of toxicity were observed when extract was given in doses of 300 mg/kg and 128 mg/kg. Conclusion: The aqueous extract from lignum vitae bark showed significant anti-inflammatory and analgesic activity with no observable toxic effects at a dose ten times that of the other extract producing these pharmacological effects. These results are consistent with anecdotal claims of swelling and pain relief with the tea from Lignum vitae bark and can provide guidelines for quantification and safety in folkloric use of this extract.

This is what I did:
Using 50% drinkable ethanol, we saturated the alcohol with Lignum Vitae hartwood shaving instead of the bark in a sealed stainless container. The liquid was filtered and a clear liquid was obtained.
Wood chips were used by these folks! So I am not starting something new except that we use 竹葉青50% alcohol content liquid.
The heart wood of Lignum Vitae is exceptional, just take a look of this small finger ring I made; the distribution of end grains are almost random filled with substances.
