Camphor is indeed a fascinating substance. In the Siddha-Ayurvedic tradition, camphor is valued for its distinct cooling properties. Traditionally, it’s made from the wood of the camphor tree, though synthetic versions exist too. Used externally, it can be beneficial for its analgesic and anti-inflammatory properties, which is why your grandmother might find it helpful for arthritis pain.
Regarding its use, applying camphor topically—usually diluted in a carrier oil—is common. It can help with pain relief and reduce discomfort. However, the key is moderation. Too much camphor can indeed be toxic, hence only a small, diluted amount should be applied at a time. Internal consumption of camphor is not recommended due to toxicity risks.
Camphor’s applications extend to treating headaches and coughs too. It may be inhaled through steam for respiratory relief or used in balms for headaches. The clarity it brings to the sinuses can alleviate congestion or headaches of vata origin, though it should again be used carefully.
Your grandmother’s practice of adding camphor to oil blends is a common one—ensuring it’s well-diluted can make its use safer. To be precise, stick to the proportions, usually about 5-10% of camphor in carrier oil.
The means of figuring this out often comes from either longstanding traditional use or consulting a professional trained in these methodologies. If you’re ever unsure, it is always a good idea to consult a knowledgeable practitioner, especially to tailor recommendations to specific constitutions and conditions. Remember, safety first: more isn’t always better, especially with camphor.
