I've now had several sessions smoking my second enhanced leaf blend, which was:
0.25g gotu kola
0.75g chamomile
0.52g spice
20ml mugwort infused ipa
20ml pau d'arco ipa

I'm very happy to report it has been a beautiful experience. The visuals have been less jagged and more holographically 3D (my kitchen has never looked so good)and I have felt a beautiful calm connectedness (although I was pissing myself laughing at how incredible the kitchen looked for a while).
I'm not measuring dose, but just going much more gently with smaller hits that are well below breakthrough, but watching carefully how much I'm burning and inhaling has given me some fantastic results.

Just harvested 1.2g from my latest pull and have infused 0.8g mugwort 0.4g motherwort 0.4g chamomile 0.4gpau d-arco (30ml lavender infused ipa + 15ml pau d'arco infused ipa)

Looking forward to trying this blend and seeing the difference.
