The Paya wan Jakkajan is in Truth only a Cicada, that has been infected by a Cordyceps Parasite. However, it has been found that the Composition found within the Paya Wan jakkajan has definite Healing Qualities, and as to whether or not it has magical power to invoke wealth, is not changed by the fact that the true origins of the Cordyceps Cicada is now known (Paya Wan Jakkajan)
In fact, despite the fact that there is no Mystery as to how an Insect can seem to be half vegetabe anymore, the combination of circumstances remains a very authentic and powerful formula according to the Principle of Ancient Sorcery. Nothing changes the element of Power.
If a Geologist were to sacientifically define the atomic properties of Lek Lai for example, it would not change the fact that peole have witnessed and experienced endless miracles and miraculous events with Lek Lai. Scientifically cataloguing something does not streal the magic away.
Apart from this, if we consider how olden days people used cords to wrap the amulets and feel the powders against their skin, instead of sealed in waterproof or stainless steel casing, we can consider the medical and healing aspects of the Sacred Herbal ingredients of the powders, as being effective in healing or preventing illnesses, and other auspicious effects which the modern day amulet scene does not enjoy, due to aesthetics demanding a nice encasement instead of a rough cord wrapping, as in olden days. Cord wrapping is something i find available and wish to offer to customers, but have not yet found a reliable person who is always available. Once i do, i shall add this option for you to choose if you prefer the olden days rustical method of amulet wearing.
I believe the Paya Wan Jakkajan Powders or amulet possess healing powers, which is not stated in this amulet description from the Temple, but my experiences studies and personal involvement with Sorcery and Herbalism, indicates to me that the Paya Wan Jakkajan is indeed a very protective Health Maintainer
