Palo Santo literally means holy wood and, just as white sage, originates from the native Indians in South America. Centuries ago they already used it during ceremonies to clear the aura and to heal from negative influences. In Europe too, people choose to buy the holy wood to clean their houses or just for the fragrances in its purest form.
The fragrance can be described as a warm, woody and light aroma with a sweet touch that sometimes slips through. In comparison with white sage (that is also used for the same purpose), Palo Santo gives off a very mild odour. It has a natural and therefore spiritual smell, and is perfect to purify your home.

Crystals come in different shapes and sizes, and some are small enough to be considered a choking hazard and therefore unsuitable for children under 3.
Children should always be supervised by an adult when playing with or handling crystals, as they are not your traditional “toy” and do require extra caution. For example, some may be toxic, whether touched, ingested, inhaling dust particles or when mixed with water. Others can be sharp in raw form, or when shattered or broken - some can be razor sharp.
When buying for children, ensure you have carried out your own research and that you understand which crystals are the most suitable.
A list of resources can be found below that will help you to decide. A good start is to look for 'health risks' sections and 'hardness' which are extremely useful.
