I used 40g of shredded MHRB. This was a A/B extraction using citric acid, toluene and NaOH. With NaOH the pH was raised to 13. After that I did a two day long pull with toluene mixing occasionally. After that the toluene was evaporated and this is the result. The brown/reddish colour is from a little water that escaped into toluene. What do you think ?
