The Efficacy and Uses of Castor Oil Plant
In traditional Chinese medicine, the castor oil plant is both a valuable remedy and a highly toxic plant, a seemingly contradictory nature that has confused many. This article will delve into the dual nature of the castor oil plant from a scientific perspective, revealing its unique medicinal value and principles of safe use.
I. Analysis of the Medicinal Value of Castor Oil Plant
1.1 Natural Solution for Lubricating the Intestines and Facilitating Defecation
Castor seeds are rich in ricinoleic acid, which can stimulate the nerve endings of the intestines and enhance bowel contraction function. Clinical studies have shown that a reasonable dose of castor oil can increase defecation efficiency by 40%, especially suitable for elderly patients with constipation. It is recommended not to exceed 0.5g per day, and the best effect is achieved when taken with warm water.
1.2 Secret Weapon for Surgical Treatment
Applying crushed fresh castor leaves externally contains ricin protein with targeted antibacterial action. Experimental data show that the inhibition rate against Staphylococcus aureus can reach 78%, especially suitable for the early stage of carbuncle. It is necessary to change the dressing every day and not to use it for more than 72 hours continuously.
1.3 First Aid Helper for Sports Injuries
Castor oil hot packs, by promoting local blood circulation, can increase the permeability of capillaries by 300%. Used in combination with turmeric powder, it can increase the recovery rate of acute soft tissue contusions by about 35%. It is recommended to control each hot compress session to 15-20 minutes, with the temperature maintained at 50℃.
II. Key Points for Preventing Castor Plant Toxicity
The LD50 of ricin toxin is only 0.02mg/kg, equivalent to an adult accidentally ingesting 3 raw seeds being fatal. The incubation period for poisoning can last up to 18-24 hours, initially manifesting as mild symptoms such as nausea and abdominal pain. It is recommended for home use: ① strictly distinguish between medicinal and ornamental varieties ② clearly label storage containers with warning signs ③ immediately wash children's skin with soap solution after contact.
Modern pharmacology has controlled the ricin content in castor oil to below 0.003% through low-temperature cold pressing technology. However, pregnant women and individuals with impaired liver and kidney function should still avoid its use, and stop using external preparations immediately if skin rashes appear.
