LLWYNYWORMWOOD - New Royal Residence
LLWYNYWORMWOOD or Llynwermood, site of one of the romantic but sadly "Lost Houses of Wales", is a name with tantalising but unproven connections with the herbal traditions of the Parish of Myddfai.
Physicians of Myddfai
during the thirteenth century, Myddfai was 'much frequented by physicians among whom was Rhiwallon, who, in conjunction with his three sons, during his residence here distinguished himself by a manuscript treatise on the practice of physic'. This was Rhiwallon of Myddfai, physician to Rhys Gryg (Rhys the Hoarse or the Stammerer), Lord of Dinefwr and Llandovery castles, during the first half of the 13th Century. Under the patronage of Rhys Gryg, Rhiwallon and his three sons, Cadwgan, Gruffydd and Einon, made a collection of medicinal remedies which are known today as the 'Recipes of the Physicians of Myddfai'.
