Collection of Drug Substances

Though the aphorism of the Organon of Medicine and its certain portion are not directly connected with the process of collection, yet the advices given by Hahnemann forms the fundamentals of preparing a drug, in which the process of collecting a drug substance is an important part for the genuineness of the drug so prepared. In aphorism 264 of Organon of Medicine, Hahnemann holds, “The true physician must be provided with genuine medicine of unimpaired strength, so that he may be able to rely upon their therapeutic powers.” In aphorism 66 of Organon be also emphasises that “substances belonging to the animal and vegetable kingdoms, possess their medicinal qualities most perfectly in their raw state”. As such advices of Hahnemann are to use fresh animal and vegetable drug substances

Vegetable Kingdom – Purity and genuinity of the original drug substances must be ensured. All vegetable drug substances should be procured fresh, as far as possible, except the substances which has to be imported from outside. It should be collected only in healthy or well developed state; free from worms, insects, or as per direction of the particle drug preparation given in Homoeopathic pharmacology. All those are in decayed state should be discarded.

They shall show no discolouration, abnormal odour, slimness or any sign of deterioration. The wild ones are preferable to cultivated ones. They should be collected when their medicinal virtue is greatest. They must not be packed too closely in carrying; and be used quickly in preparing the substance after collection, so that they may yield their full medicinal strength unchanged. Never collect them during morning dew, nor immediately after a shower, nor during too heat of the day. They should be gathered when the weather has previously been sunny and dry, and just after disappearance of the morning dew.

Cleaning of the drug materials, so collected, should be done carefully so that any part of it is not erroded. Never wash with profuse water; if become unavoidable, use only too little water for washing. Exotic drug substances should never be imported in powder form, and without proper identification of their genuineness (vide Organon of Medicine-aphorism 268).
