Psora is considered the fundamental miasm in homeopathy, representing the basis of many chronic diseases. Its manifestations are varied and can include:
\begin{itemize}
\item (A) Aggravated in morning and from eating meat: Some psoric conditions can show aggravation in the morning. Aggravation from eating meat is also associated with certain psoric remedies and constitutions.
\item (B) Ameliorated by cold: While some conditions are ameliorated by cold, this is not a general characteristic of Psora. Some psoric conditions might be aggravated by cold.
\item (C) Always hungry with burnt taste of mouth: Increased hunger is a feature seen in some psoric states. A burnt taste in the mouth can also be associated with certain psoric remedies.
\item (D) Stupid, dull senses and especially stubborn: These mental and emotional symptoms are more strongly associated with the Sycotic miasm. Psoric individuals may exhibit anxiety, irritability, and restlessness, but not typically dullness of senses or stubbornness in this specific way.
\end{itemize}
Therefore, statements A and C are more consistent with certain manifestations of the Psoric miasm.
